  1. Hi all, I have been asked by a client whether we can setup load balancing for their existing Processwire site. From my investigations on Google and within these forums, it definitely seems possible but as a newbie with a basic understanding of the subject im a bit lost. Does anyone know of any existing tutorials for settings up load balancing with PW? What items would need to be changed on their current stand alone install, is there a list of best practices worth consulting etc? As I understand it we would need to have some sort of copying mechanism (rsync script most likely) in order to make sure any uploaded assets are shared between the main server and the fallback ones, other than that im not sure what else would need to be ammended. Any thoughts/help would be greatly appreciated.
  2. 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 of size. Currently we count: 140 Templates (Some have 1 page, some have >6000 pages) 313 Fields ~ 15k Users (For an intranet portal? That's heavy.) ~ 195 431 Pages (At least that's the current AUTOINCREMENT) I think we came to a point where ProcessWire isn't as scalable anymore as it used to be. Our latest research measured over 20 seconds of load time (the time PHP spent scambling the HTML together). That's unacceptable unfortunately. We've implemented common performance strategies like: We're running on fat machines (DB server has 32 gigs RAM, Prod Web server has 32gigs as well. Both are running on quadcores (xeons) hosted by Azure. We have load balancing in place, but still, a single server needs up to 20 sec to respond to a single request averaging at around about 12 sec. In our research we came across pages that sent over 1000 SQL queries with lots of JOINs. This is obviously needed because of PWs architecture (a field a table) but does this slow mySQL down much? For the start page we need to get somewhere around 60-80 pages, each page needs to be queried for ~12 fields to be displayed correctly, is this too much? There are many different fields involved like multiple Page-fields which hold tags, categories etc. We installed Profiler Pro but it does not seem to show us the real bottleneck, it just says that everything is kinda slow and sums up to the grand total we mentioned above. ProCache does not help us because every user is seeing something different, so we can cache some fragments but they usually measure at around 10ms. We can't spend time optimising if we can't expect an affordable benefit. Therefore we opted against ProCache and used our own module which generates these cache fragments lazily. That speeds up the whole page rendering to ~7 sec, this is acceptable compared to 20sec but still ridiculously long. Our page consists of mainly dynamic parts changing every 2-5 minutes. It's different across multiple users based on their location, language and other preferences. We also have about 120 people working on the processwire backend the whole day concurrently. What do you guys think? Here are my questions, hopefully we can collect these in a wiki or something because I'm sure more and more people will hit that break sooner than they hoped they would: - Should we opt for optimising the database? Since >2k per request is a lot even for a mysql server, webserver cpu is basically idling at that time. - Do you think at this point it makes sense to use ProcessWire as a simple REST API? - In your experience, what fieldtypes are expensive? Page? RepeaterMatrix? - Ryan, what do you consider as the primary bottleneck of processwire? - Is the amount of fields too much? Would it be better if we would try to reuse fields as much as possible? - Is there an option to hook onto ProcessWires SQL builder? So we can write custom SQL for some selectors? Thanks and lots of wishes, Pascal from Mobile Trooper
  3. I'm building a site and i noticed that loading time is very slow when we enter the site address for the first time. It takes about 1 minute or more just to start loading files and displaying the content. However, after that period it's very fast and everything is ok. Once the page(s) is/are loaded, i can refresh them quickly and without any delay. any one faced like this problem? and what can i do to resolve it. more details: ProcessWire 3.0.80 hosted type: VPS this message appear in admin dashboard: " Warning: your server locale is undefined and may cause issues. Please add this to /site/config.php file (adjust “en_US.UTF-8” as needed): setlocale(LC_ALL,'en_US.UTF-8');" The site: http://almanassah.net
  4. Let's say I have 500 Eventpages or more with differen content fields(date, title, textarea etc..). I would display all events in a list like this: $events = $pages->find("template=event, limit=10"); echo "<div class='event-container'>"; foreach($events as $event){ echo "<div class='event-detail'> <h1>$event->title</h1> <p>$event->short_description</p> </div>"; } echo "<a class='load-more'>LOAD MORE</a>"; echo "</div>"; Now I want to make the load-more link to display 10 or 20 more events without reloading the page and showing a loading gif/text while its rendering the other events, when clicking on it . How can i achieve this? I know that i could use pagination for displaying this heavy amount of results but the customer doesn't want that because it don't fit in the design of the website. Can I probably achieve a combination with Pagination and Ajax, or are there other ways to do it?
  5. Hi everyone, let me first start off by expressing how much I love Processwire, I've succesfully integrated it with about 8 sites now and I'm just so in love with the simplicity (we love you ryan ) I was wondering how processwire scores on the performance/serverload front, how much processwires can I run on my VM with how much ram and are there any recommoned server apache settings? currently I'm running an ubuntu with 4GB ram and 3 cores (1,6Ghz each), I'm using php 5.1 with mod_cgi and the 8 processwire sites use about 1,6GB of RAM, having about 50k visitors/month across these sites I'm wondering how processwire will perform in case of 100k - 200k - 500k - 1M visitors, will the session system last (I noticed it's writing a cached file to the filesystem)? also: what's the limit with the "new Page();" command, is it creating a new directory for every created page, what's the limit (the filesystem? the amout of ram?)
