slow and laggy

[joe_g]

Hey, so we gotten a bit further in evaluating this page grid. The main issue we have now is that there seems to be an exponential slowdown with the amount of elements on a page. It could be something else, but it seems to be a pattern.

Scrolling and moving things becomes laggy so it becomes hard to work with. But it could also be that there is something wrong with my setup. I could give you the url as a PM in case you'd be interested in having a look.

Hi @joe_g you can send me PM with your link and I will have a look.

Please make sure that you are running the latest version, because I made some performance improvements a while ago. I have sites that have more than 150 items and they run fine. But it's true that the performance can take a hit (in the backend) when you have lot's of items on a page. It also depends on the kind of items, e.g. having lots of autoplaying videos or sliders is not good for performance. I also found out that the chrome browser has the best performance and of cause it depends on the computer you are using. Good performance is very important to me and I will continue to improve PAGEGRID as much as possible, so it's always helpful to see how it works in different contexts..

I tried this on a fresh install, so far

* Crucially, dragging things seems quite fine and snappy
* Scrolling is laggy (<5 fps) IF the settings pane is open, if it's closed its okay-ish

I need to test more to see if it's something with my setup (yes, lots of video, but i doubt that should affect javascript execution?!)

@joe_g I just pushed an update that should make the scrolling perform much better. Can you try the latest version and report back if it fixes the issue for you.

[joe_g]

Nice, I'll try it.

what is the best way to upgrade without losing any data? Just replace the files from https://github.com/jploch/FieldtypePageGrid and https://github.com/jploch/PageGridBlocks ?

Upgrades don't mess with data. The data model has not changed for two years and there have been no breaking changes since then. If this would change in the future it would be a major version change like 3.0. that indicates this. Still good to make a database backup just in case. 

The easiest way to update is going to the PAGEGRID module settings (Setup > PAGEGRID), open the module info und click on "Check for updates". Same can be done with the PageGridBlocks module. But you can also replace the files like you sad.

oh so simple, duh

did a quick test and things seems considerably snappier now! Very nice
