Weird timeouts, not sure if I've set the right threshholds

Hi guys,

Can anyone explain the prejudice against NFS?

Specifically, why would additional proxy hop be faster than serving files from 
I can see two points in favor of NFS:
- NFS client caches files while Nginx doesn't (yet)
- Nginx doesn't support keepalive connections to upstream, hence additional 
latencies and traffic for TCP handshake/finalization. NFS doesn't have this 
issue since it typically works over UDP.

I do have a couple boxes serving a lot of traffic (mostly PHP) from NFS. It 
works just fine, though it did take some NFS tuning.
