Umm, what kind of request profile did you send from ab? What kinds of  
resources are being requested?

I find nginx to be noticeably faster than apache on static files with  
serial requests, and many times faster using high levels of  
concurrency. For dynamic requests to PHP over FastCGI/tcp, it's also  
faster, has better concurrency and uses very significantly less  
system resources.

On a dual-core 2ghz xeon with 4GB RAM nginx served nearly 500k PIs of  
a site with a ~1mb home page weight (yes, i know ;-) - designers ...)  
in one day without ever swapping and without system load going above  
2. Just trying to mimic that load using ab against Apache brought the  
machine to its knees in minutes. Turning up the concurrency on ab  
causes Apache to starting eating RAM and CPU like nobody's business,  
whereas nginx handles it smoothly and quietly.

I'm relatively new to nginx but on the site mentioned above I run 2  
worker processes with 8192 worker_connections.

This is interesting ... I use keepalive_timeout of 4 or 5 seconds
