The first time a page loads, it gets "created", but after that there is no reason it should not be fast, since it just loads a cached html page.

It would only check for images stored in cache, that are actually ON the page you are loading. That is the whole point with the cache system, and there is nothing wrong with that specifically. If the resized-image is not yet created/cached, it will have to resize an image, and that is a slow process.

How many photos do you have in your gallery? That sounds like a suspiciously high number I admit ...

jeroenvermeulen.nu wrote:In some cases the PHP will check this folder

It doesn't generally "check the folder", but it checks for existence of a cached file, and that is the whole point of cache. Also, it will only check for the cached file when the page is created first time, because after that the page instance itself gets cached as a html resource (no more checking).

Not quite sure what you mean by this. The original image is there, and server may load it obviously, but it doesn't "check" it or anything. It just gets loaded, and in some cases counted for the sake of the menu and other things.

X3 should not be slow, so yes would be interesting to look into this. It does sound very strange that you have 12000 photos in the /images/ cache specifically. Are you sure the other cache folders are created, and have subfolders inside?

You mean you have approximately 5000 images in your gallery then?

jeroenvermeulen.nu wrote:Inside /cache/ there is /rendered with 12500 files and /request/ with 125000 files.

If you have 5000 images, then 12500 cached image requests/renders is reasonable. For each image in your gallery, it will produce 3-5 resized images based on your layouts, crop settings, and what mobile devices had visited the page. This is how cache works, so that your server doesn't have to resize every request in realtime.

I am curious though, you must have been using the gallery for a while for that cache-library to build up ... If you start with an empty cache, and visit a single page with 100 images, then 100 renders/requests will get populated into cache (perhaps with a few more if you have images in the menu). What Im trying to say, is that this is a progressive process, where image renders/requests get added to cache as pages are visited.

On paper, I can't see anything wrong, unless there are some strange/special circumstances. If you had a link, I could at least check myself ...
