Ok, thanks for the help. The problem is, there is no "slow action", it's just the login page, it sends one query to the database (10 records total), then redirects to a list of matters (it's just a "Matter.find(:all)). The problem I'm getting is precisely this: there is nowhere to optimize...
The application is a "Matter chooser" (something like this, sorry, english isn't my primary language): Students login into a page, choose a couple of matters, and then submit a form. Problem is, each matter has a limited number of students, so the first one that submits gets the matter. So, the application stays online for two days, and in the first 3 hours of the first day, there are a lot of students (200+) that tries to login, and when passenger timeouts their connections, keep pressing F5 to update the page... and that is when things get complicated, because everyone that already logged-in simply gets a timeout screen. It's no use trying to optimize anything, because this happens only in the first 3 hours, for example - after this, things go back to normal... Suggestions? And, somebody said I could limit simultaneous connections in passenger, how do I do this? Thanks!
