<div>hi, sysoev,</div><div><br></div> for proxy, can nginx give an new option, for example client_max_body_size_in_buffer, it will be served synchronously from client <div>if client body size is greater than client_max_body_size_in_buffer ?<br>

Is there a page about performance optimizations in the wiki? If not I think it would be useful to create one so this and other performance related information can be collected there.<br>

Good!<br>
One thing we must do is tuning. Your experience on temp files is useful for me.<br>

hi,<br>
<br>
<br>
last week, I did a nginx performance test.<br>
Yes, with no surprise, nginx is perfect.<br>
First, I proxyed 15 web hosts after nginx, the cpu utilization and disk<br>
IO were a little high, this was cause by the file download and access log,<br>
after I closed the access log, and changed the download to<br>
synchronization by set proxy_max_temp_file_size to zero, nginx run with<br>
little CPU consumption.<br>
So I turned more web hosts after nginx, the disk IO became some high<br>
again, this was caused by uploading, so I changed the client_body_tmp_path<br>
to a tmpfs,<br>
and disk IO disappear, and the bottleneck was the memory capacity.<br>
Finally with 50+ web host proxyed, the nginx host's CPU utilization is<br>
about 30%, and the client_body_tmp_path occupied 4-6G, the peak throughput<br>
of each network<br>
adater was 400-450M.<br>
It is a good result. Thanks you, sysoev.<br>
