Hello Ladies and Gentlemen,

We have a very frustrating problem with a NAS configuration that we recently set-up. After running a filesharing website on 8 servers for 1+ years we decided to switch to a NAS configuration. We set-up our NAS (24x1TB Raid 5) to serve files to 9 front end servers over a private switch - doing 9 servers on 1 disk(logical)... not sure if nginx can handle this. Since we've moved to the NAS BW usage has dropped significantly even though our traffic has stayed the same. Download speeds are pretty bad aswell but this is due to IO issues that are being created by NGINX. so here's the problem we are facing...

In theory nginx is creating an io bottleneck because it's opening to many times without closing. We're using nginx to serve files to our 9 front end servers - each file will stay alive though for 45+ minutes. Instead of opening it for 10 seconds, reading into memory, and closing - it's opening it for 10 seconds, reading into memory, streaming it for 45 minutes, THEN closing. We ran a test with nginx and we were only able to download at 30kbps on port 182, how-ever over apache we were able to reach speeds of 20mb/s.

We've re-compiled nignx and installed the most recent stable version but that didn't fix anything.

Can someone please suggest a fix here? I've ran out of ideas...

Thank you!
