Speed with large nr videos

i now have V2.6 and also the same speed issues
on the site where there are 8500 videos it takes 10 to 15 seconds to load the video page

actually, not all videos load slow
some are pretty quick like this one

but another on the same site, same DB is very slow, most are slow

i see no difference why one should load slow and the other fast
the site is running on a dedicated server dual opteron 2.8Ghz and the load remains below 1
also when i load the slow video (above) and in another window open the "fast" one
the fast one is finished sooner, so its not that the server is overloaded
i also checked the MySql entries for both videos, and there seems to be no strange things there
(like funny characters or such)

klaas

i can give you access to the server to debug it

i deleted 1500 videos, now its faster
apperantly there is a 8000 video limit for speed
