November 12, 2008 at 19:13Slow UPDATE vBulletin - what's the catch?
I bought a license for vBulletin for two forums. On one - it flies round the clock (about 20,000 registered users), on the other - it starts to slow down in the evening (120,000 users).
Attendance is the same - 50-100 people online. I launched Debug Mode on the braking forum , it turned out that the most recent request took up to 16 seconds!
Moreover, it is not necessary once or twice - the request can be executed a couple of times normally (thousandths of a second), or maybe 16 seconds.
I think that blaming the size of the database and the number of users would be wrong, although the thought was to remove those who did not attend the forum.
