I have a test install of gallery2 (2.1.2) on my site, because I'd like to get away from the micromanaging I am currently doing with images. Unfortunately, I've found the site to be slow regardless of load (currently 5 and still having problems). I've generated all the thumbnails, but the main page regularly takes 10+ seconds without accelleration. The album pages take about 3-5 seconds. If I max out the accelleration, it takes 2-3 seconds per page, which is closer to acceptable. The problem is, what happens when the server is really under load? Most people won't wait more than 8 seconds for a page to load.
I've used Gallery2 on dedicated servers before and had no problem, but that doesn't really say whether Gallery2 is efficient. I've disabled about half of the modules in an attempt to speed it up.
Is this an issue with DH?
Could it be due to the install being "multi-site" ?
Is Gallery2 just this inefficient?
Is there a better system out there?
I really just need a gallery that looks decent, can be set to automatically generate multiple sizes of uploaded images, and is easy to organize. It doesn't need to be able to support multiple users. Anyone have any thoughts?
