Hello guys

any help will be appreciate it

I have new server with 1 Gbit port speed and I installed nginx on it.  
The  
server only for downloading data.

Now there are  
TCP Connections in ESTABLISHED State

2060.0 con

the currently traffic use : 140.6 Mb/s  
see MRTG [http://server07.animedown.tv/mrtg/](http://server07.animedown.tv/mrtg/)

I have 4MB speed in my computer. if I download file by flashget/download  
manager program , the speed will be around 100 KB/s.

in the same server if I download through apache the speed will be around  
400

- 500 KB/s

you can test download speed by your self

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.
