Hi,

I've not had a detailed look at the config, but I think you're possibly
suffering by having

client_body_buffer_size 32m;

Perhaps try something like :

client_body_buffer_size 32k;

or see how it works with the default (8k or 16k depending on the platform).

Also, 25 worker processes is probably way too high. Try 1 per processor
core, or possibly even fewer.

You might also want to experiment with sendfile on.

Good luck!

Marcus.
