I've Googled until my eyes bleed but can't seem to find anything related to this problem. On one of my web sites there is a user base of a couple hundred people. Situations arise where anywhere from 15-30 people will try logging in at exactly the same time (like within seconds of each other) from the same location. The first 5 will get right in, the second 5 will get in but with a bit of a delay and anyone beyond the first 10 users will timeout and have to try again. I am wondering if anyone has any ideas about why this might be happening? Are there limits within Drupal I can adjust? Tweaks I can make to mysql? Apache config adjustments? I would be grateful for any suggestions as I have no idea how to solve this very strange problem.

Sounds like the server is
Sounds like the server is underpowered. If the first people to log in (successfully) find the site slows down then this would tend to confirm it. On the other hand if those people still find the site responsive then I'd be confused since logging in is not a particularly demanding operation but possibly Apache doesn't have enough worker threads so can't cope with the number of simultaneous connections. Similar point for MySQL. What does your host say?
