Uploading a small "hello world" file using upload_module takes about 2 seconds, while not using upload_module and passing it directly to my fastcgi is almost instantaneous. To debug the problem I modified the upload_module code and added a debug statement at the end of function ngx_http_upload_handler, and another at the beginning of the function ngx_http_read_upload_client_request_body_handler.

Using nginx_upload_module-2.0.9

2009/06/22 12:02:56 [error] 16737#0: *1 returning ok in ngx_http_upload_handler, client: 127.0.0.1, server: myhost.com, request: "POST /upload/this HTTP/1.1", host: "localhost:81"
2009/06/22 12:02:58 [error] 16737#0: *1 67964 begin ngx_http_read_upload_client_request_body_handler , client: 127.0.0.1, server: myhost.com, request: "POST /upload/this HTTP/1.1", host: "localhost:81"

Notice the 2 second delay between those calls. Are there other settings I could tweak to get that 2 second delay down?


Here is my nginx.conf

To post to nginx, I'm using
echo "Hello world" > /tmp/hworld
curl -F 'file1=@/tmp/hworld' 'localhost:81/upload/this'

Thanks for any help!
