After the conversion from Apache [+passenger] to Nginx [+unicorn] overall throughput went up by a factor of 3.

I noticed a similar gain (10-12 req/s to 25-30req/s) for action cached pages after switching out nginx+passenger for nginx+thin. This is on a 256mb slice, and seems totally counter to the general opinion that passenger is great for VPSes.

Have you tried nginx/passenger? I ask because I wonder how much of that gain is part of switching to nginx rather than switching to unicorn...

on a separate application and server, yes, and it seems faster than apache/passenger, but it still suffers from the 'passenger choke' where touching tmp/restart.txt seems to pause all web traffic for 10-15 seconds, so we never considered it here...
