May I add my severe problems here as well:
Since four weeks now (and at about 10.000 photos) our gallery dramatically lost speed and therefore our users tragically visit only for a short look and leave then. (Due to our rare photo-themes we had up to 2.000 viewers per 30 minutes before, now there are about 100 viewers per 30 minutes).
I installed all latest versions of apache, php, Imagemagick, mySQL, vB
, and photopost, no chance to get it back faster again.
It seems to me that first it hangs for some seconds, then brings the empty frames and then is takes up to one minute to load one page. I have to add, that speed varies.
The only thing I noticed, since I have these speed problems, is that CPU-Load is rather high, with peaks up to 80 or 90 percent (Windows 2003, P4, 3 GB Ram).
So I enabled MySQL_slow_log which gets about 1 to 3 entries per second of this kind:
Content visible to verified customers only.
The home of our gallery is: Haupt-Index - SAGEN.at FOTOGALERIE
I would be very happy on advise
