How slow is it? I use OS X and nginx as a frontend, but not to mongrel. File uploading works fine for me.

Well, I turned off sendfile in config. I also changed a bunch of parameters per an email I received from Dave Cheney (thanks Dave!). No luck.

Just for laughs, I installed and configured Swiftiply with Mongrel and turned off Nginx. Same issue.

So, then I turned off Swiftiply also and started just one mongrel and told it to listen on port 80. It worked great. File uploads were much faster.

So, if I am having the same issue when proxying from either Swiftiply or Nginx, but I don't have the slowness issue when I don't proxy and just go straight to the mongrel instance, this tells me the problem is not with Nginx, but must be some setting on the OS X server.

Does anyone know what would cause proxying in general to be slow on an OS X server? I know its not the network speed from the browser to the server, because when I was connecting directly to the mongrel instance without proxying, file uploads were fine.

Sorry for asking this (probably) non-nginx related question on the list, but I started it here, so I figured I would ask one more question.

Thanks.

I have a rails app running on an OS X server, using nginx as the web

server, proxying to a mongrel cluster. File uploads from the user's browser are painfully slow when going through nginx, but if I target an individual mongrel instance in the browser, the file upload is fast. I have the latest mac ports version of nginx installed ( 0.54, I believe).

Any ideas? I tried changing the log format, as suggested in a reply

to

someone else's post, but could not get nginx to start, so I don't know if nginx has to be compiled with a particular flag in order to include the log format config directive in nginx.conf.

Any help, suggestions would be greatly appreciated.

Try turning sendfile off in the config.
