Hi everybody!
We have installed vB 4.1.0 PL2 on a brand new dedicated root server (4GB RAM, Dualcore 64bit, CentOS) but the overall performance is rather poor. No more than approximately 200 users are using the forum at the same time, averaged over 45 minutes (Most users ever online was 252), usually it is less than that.
At some times, the board takes very long to respond, even time outs occur from time to time. At the same time, other files not related to the forum can be retrieved without problems. Especially when using the search attachment feature in the ACP, that regularly triggers a database error ("too many connections"). Further, Firefox quite often displays the following error message while accessing the forum. Other pages using the same web server (apache) are not affected. Reloading the requested page usually solves the problem temporarily.
I've increased the maximum number of connections in the my.cnf file up to the following values:
max_connections=1000
max_user_connections=100
Unfortunately, that had no effect at all. Attachments are stored in the file system.
The same server hosts a couple of very small sites with almost no traffic. Those are not affected. Pages are available very quickly while vB4 just lags. Also, the "too many users" database error does not affect other scripts accessing the database. While that error message is displayed instead of the Forum, other pages accessing the MySQL server do not show any signs of problems. Unfortunately, this behavior cannot be reproduced and I do not see any relation between number of users online, time of day, ... Just when searching "new" attachments, the "too many connections" database error occurs very often (not always, though).
Any suggestions for improvements?

The connection to the server was reset while the page was loading.
