Image processing very slow in Revo?

I've been struggling to get the ModX Gallery Galleriffic fast for a while now. In my search to make it faster (thumbnail loading), i've tried a lot of things (see also: http://forums.modx.com/index.php?topic=67275.0 ).

Recently, I've tested gallery without the Galleriffic plugin and noticed thumbnail loading is still very slow. Further testing showed that even custom PHP pages within Revo (without the use of Gallery or other ModX plugins) are slow when loading thumbs. When the custom PHP page is not included in ModX it's fast.

This keeps me guessing on how I can get Revo to be faster. The biggest problem I have right now is the Gallery/Gallerriffic loading times, but also the custom PHP page is a pain in the ***. I've noticed that my server doesn't support Imagemagick (and the admin doesn't want to install it for security reasons). I do have GD. Might this be causing the slow performance in Revo? I'm talking about loading times for 100+ thumbs.

Any help would be great!

I'm not familiar with Gallerific, but is the problem happening with the listing snippet or the thumbnails being generated on the fly? Have you cached everything that can be cached?

Yes, everything that can be cached is cached. Even for non-dynamic content everything you pass trough ModX goes 10 times slower than by not putting it trough ModX. sad

Anyone got any tips on how to increase performance in Revo?

I've moved away from Galleriffic to the "regular" Gallery, with Colorbox. Still, things go painfully slow. What is it with ModX and images? Am I the only one with this problem, am I doing something wrong? Please help! sad

Hello,

This sounds more like a server issue, can you tell us more about your hosting environment?

This is what i've got from the control panel:

The server is located in the Netherlands, just like me. The only thing I know that might be an issue is the absence of Imagemagick. GD is installed, but the server admin doesn't want Imagemagick on his server. Could this be causing the speed issue? It's shared hosting on a rather big account. Performance outside of ModX is fine.

Pages that don't contain any images processed trough Gallery or PHPthumbof are normal speed. I've really tried everything, but I can't seem to figure out the poor performance I'm getting. I've looked in the error log, and it doesn't show anything strange. CSS and JS are compressed. Really the only quirk I have is with images trough Gallery, but somehow I highly doubt that it has anything to do with the Gallery addon itself...
