Poor performance in serving of static files

[Jürg Lehni]

I've tried increasing worker_processes and turning off sendfile already, no difference. The modules did not seem to affect performance, as I also compiled a fresh Nginx from source myself and saw no difference. I then switched back to the package provided by Debian Backports. I am now using the package nginx-light, with still the same performance.

And without having done any proper benchmarking, hitting any of these rendered type pages after that just feels much slower and less fluid on Nginx. I am really surprised!
