  1. Hi there, while developing a sideproject which is completly build with ProcessModules i suddenly had the urge to measure the performance of some modules 😉 as a result, say welcome to the FlowtiAppPerformance module. It comes bundled with a small helper module called FlowtiModuleProfiler. In the first release, even though you could select other modules, it will track the execution of selected Site/ProcessModules. This will give you the ability to gain insights how your Application behaves. The Main Module itself will come with 2 Logging Options, Database or PW Logs. Select D
  2. ProcessWire has builtin cache system (enabled per template basis). Why ProcessWire is not using HTTP headers Last-Modified and If-Modified-Since when cache is turned on? It seems that using this headers could increase performance and is quite easy to implement.
  3. Hello, One of our sites is suffering from very slow boot times, and I'm not sure how to diagnose the problem. Here's a grab of the debug panel in Tracy debugger after loading the homepage. A have a couple of questions - Are all of the times listed separate items, or are some of them a breakdown? I ask because the number shown in the tracy debug bar is the total of all of the items but the wording suggests boot.load.modules, boot.load.fields etc are a breakdown of the boot.load. How do I find out what these times consist of? Currently, when using the site, a
  4. Hey Ryan, hey friends, we, Mobile Trooper a digital agency based in Germany, use ProcessWire for an Enterprise-grade Intranet publishing portal which is under heavy development for over 3 years now. Over the years not only the user base grew but also the platform in general. We introduced lots and lots of features thanks to ProcessWire's absurd flexibility. We came along many CMS (or CMFs for that matter) that don't even come close to ProcessWire. Closest we came across was Locomotive (Rails-based) and Pimcore (PHP based). So this is not your typical ProcessWire installation in terms
  5. What i wanna achive is a simple counter like that count up on visit (this is no problem) AND save the specific date (year/month/day) of the count... in the end i will be able to get visits per day/per month/per year in a nice and dirty graph. Just to have a way better simple counter system. Should i only go with a complex setup of pages like this: --stats (home template for pageviews) ----2018 (year) ------08 (month) ---------29 ->page_views (integers on every day template) ---------30 ->page_views Or just simple use: --stats (home template for pag
  6. Long but well written, detailed and informative article written by an Engineering Manager for Google Chrome about the true cost of Javascript and what you can do to alleviate some of that cost. Must read! https://medium.com/@addyosmani/the-cost-of-javascript-in-2018-7d8950fbb5d4
  7. Hello, I want to develop an eshop with processwire + padloper + any needed module (ex. ProCache n stuff). Right now, the eshop is in CS-Cart and I hate it. Will pw be able to support "proper" eshop features such as some simple sales graphs, 1k+ products, shipping methods & costs, user registration, search history, order status, payment status (for bank transfers for example) etc. For example I'm thinking that products and orders as sub-pages will be problematic (10k+ sub-pages) I also want to know if it's actually worth it or if it would be better to move to a bigger platfor
  8. Hello, i have encountered a random problem with my processwire page. I have build a simple php file where i include the processwire index.php and run 1 simple database query and echo the total execution time of the script. I call this file periodically to check the performance of the page. Most of the time the execution time is under 0.5 seconds, but some times i goes up to over 3 or 4 seconds. The database query takes very little time, so the problem seems to be in the code called in index.php. I checked my server and database metrics and they look perfectly fine. Has anybody exper
  9. Hey guys, I have two performance related questions. Question 1. find vs get In my setup, I have a template called 'article,' which is a child of 'articles.' There are two ways to get all articles. This: $pages->get("/articles")->children; or this: $pages->find("template=article"); And if I wanted to further filter the articles by author , the queries would look like these: $pages->get("/articles")->children("author=john"); and $pages->find("template=article,author=john"); I think "get" would be faster in such situat
  10. We have a big selector which we have broken down into 3 chunks to return a list of notes (pages) with repeaters as follows. We also allow the user to filter the results. The problem we have is that the page currently takes nearly 10 seconds to process results. Is there anything we can do to improve the performance of this? I wonder if it would be worth bringing the filters into each of the find()s. I assume that caching here wouldn't work due to querystring parameters? $selector = "template=horse-note"; // Notes with unread comments (date order, most recent first) $notes_with_unread_comment
  11. Helo, I have a site running on PW 2.7.2 stable that is solely used for data logging. No frontend code at all. Every log entry is saved as a page. The template for the log pages has 5 fields: The channels field is a Pro Tables field with 4 columns: The data stored for the logs looks like this: Apart from that there are only about 10 more pages and about 12 templates sharing 12 fields amongst them. The logs are coming in from another PW site via REST API and are stored every minute. So no big overhead there. ATM there is only one log coming in every minute. But for the futur
  12. Just a small question on selector performance and room for improvments... i use a little function that renders me all archiv links like /2015/ /2014/ and so on...all years that are _used_ in the article system... This cause a selector without limit...and there will be many posts/articles in future now there are about 40 - it will scale up to 100 fast and more will follow...so here is the question about caching the find query or using other code...? Basic information i work with a URL segment approach that show me /year/ and /category/ overview pages. (Category or not the problem while
  13. Having milliseconds retrieval time in the PDO querylog would shed light on an otherwise dark corner of performance monitoring. When the MySQL adapter transitioned to PDO, the query log timings were omitted from the log output. The older MySQLi logs included milliseconds elapsed, which was helpful in surfacing retrieval bottlenecks. Attempts to manually profile PDO queries often run up against a profiling_history_size of 100, a limit imposed by MySQL itself. That is to say that getting a complete list of timings over the course of serving a page isn't always easy. Having these added back to t
  14. Does anyone have a recommendation for creating a MySQL connection pool on an Apache httpd server? Every invocation of PW is slowed on this system with about 1 second taken up before any useful work is done, primarily in establishing a database server connection. This is on a VPS, so admittedly it isn't fully under our control, but still...
  15. Hi guys, i've just a simple question of a little textformatter that i use for replacing different textvalues. I'm not that experienced PHP professional so i asking before i get in possible troubles... Setup is a "Glossar" like page holder with glossar_entries of various types like (abbr, internal link, external link) In my textfields i use pipes to set a term of that glossary like ||PW|| is great! i can preset ||Internal|| and ||External|| links and reuse them in every textblock...if i change the glossar entry on every page i use this it will automagic change... so far so simple (i've
  16. Hello everybody, I'd like to use the images field as an upload UI. One image field would hold 1000+ images and I am wondering how this would perform in the backend. I would only need the upload functionality. No need for thumbnail display, ordering etc. Has anyone experience in using an image or file field with very large quantities of images? Or is there an alternative upload UI for PW that stores all images to a single folder? EDIT: I don't need to upload 1000+ images in one go.
  17. Hi, i noticed on my sites and also on other processwire sites, that the time to the first byte is quite long (> 500ms). Is there a way to speed up this waiting time, without using plugins like ProCache? i benchmarked some sites from the showcase and from Processwire weekly and nearly all of them perform bad at First Byte Time. is this related to Processwire or just standard behaviour for php/cms sites? Here are the tests: First Byte Time - Grade F URL: http://c-logistic.de/ Test: http://www.webpagetest.org/result/150601_J7_3992e9491b6acf72f73f10441880e6a2/ URL: http://von-ber

  19. Hello, I'm in the process of building a web application with PW that delivers data to mobile clients. There will be up to 1000 requests per minute to my webapp (later maybe more). Every request triggers a search through up to 1000 pages and compares timestamps that are sent by the mobile clients with the request to timestamps that are saved with each page that is being searched. The timestamps are saved in PW in their own table in the DB together with a page reference id which makes searching pretty fast. For my search I use: $ads = $pages->find("template=advertisement, ad_server=$
  20. Hi, Coming from modx (Evolution) I found one restriction (which was later solved in Revo version) was a page limit of between 2000 and 5000 pages, after which performance apparently took a nosedive. I never fully tested this but it was a restriction I was always aware of and it did prevent be building a couple of sites. I would be interested to know if there is a theoretical "page limit" in PW, or alternatively has anyone developed a site with 5000+ pages and how well does it perform. How does it affect caching? Thanks
  21. What is the difference between $a->add($item) and $a->append($item)? I know there are some speed improvements in 2.5.x (comparing to 2.4) but is there room for more? I'm using caching in templates, I can not use ProCache. Looking at timers in debug mode I see: boot: 0.2262 boot.load: 0.1925 boot.load.fieldgroups: 0.0506 What is going on between loading fieldgroups and load?
  22. Hi all! I updated some of my PW installations (v. 2.5.3) and one is facing performance issues. A module (on that site) sends about 400 emails and it took usually 90 seconds. Now it takes more than 11 minutes. Before it was about 5 mails per second on average. Now it takes about 2 seconds per email. I didn't change the code – I just updated PW. That's how my module works: Editor creates a page (Newsletter template) Editor adds child-pages (Section template) Editor pastes into a textarea all emails/subscribers (and hit "dispatch") Module grabs the Newsletter page ( $mailtemplate = $newslett
  23. Hey guys, I was wondering... Does the number of used/installed modules affect on site performance?
  24. Hi guys, I have a category template and articles in different category ( articles template ). category1 - articles category2 - articles category3 - articles - articles I am listing all the articles via the selector "template=articles" . When the category is made as unpublished or hidden then also the articles are displaying. Is there a way other than doing $category = $pages->find("template=category"); $category_ids = $category->__toString(); $articles = $pages->find("template=articles, parent=$category_ids"); I can get only the articles for published ones? Thank you
  25. Hello together! I am working on a new site with pw. It is just a little gallery site. In the past I used MODx for this but since version 2 (Revolution) this CMS is pretty oversized and extremly slow. So I decided to give it a try with pw. So far so good. On my local dev environment a basic page needs about 1.1s to get delivered by the server (only html). A short and superficially check (= end_ts - start_ts) has shown that "new Processwire()" took approx. 1s. Is this a "normal" loading time or is there any space for performance improvements. Imho 1s seems a little long... :/ Thanks guys! Chr
