50 to 80 is the range I've seen. You should also set up the load balancer in such a way that it never sends more than one request at a time to any Mongrel process, when a Mongrel is overloaded even for a few minutes, it will allocate another up to 50 Mb and never release it back. 512 Mb is the minimum you need for 4 Mongrels, which is usually enough to exhaust CPU / system bus speed limits on a commodity Dual Core box. In equally vague terms, it should usually be enough to handle a normal slashdotting (sustained load of 10-20 hits per second) with a reasonably well-tuned Rails app and no page caching. Assuming your database is on another box. Having said that, there are applications and applications. Something like a blog (99% page-cached traffic) can be hosted on a 100 Mb VM with a single Mongrel behind Apache. -- Alex Verkhovsky RubyWorks --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Deploying Rails" group.
