Uploads with nginx 1.0.12

Indeed, the high load is caused by php-fpm. I was wondering if there was
any alternative config to keep fpm from spiking (like, any built-in helper
to pass the final location without any plugin…).

I will look into the compiled module. I'm not very comfortable with
compiling it on the cluster of servers which were previously using dotdeb,
but it's better than nothing (uh, tips to keep the debian specific
structure when compiling?).

Thanks for pointing me out!

I assume that since the spike occurs *after* the upload, the culprit is
PHP, not Nginx?

Assuming the spike is caused by PHP, you might take a look at the
nginx_upload module, which will handle the entire upload process for
you, and just hand your PHP script a path to the uploaded file (along
with a few other parameters).

Here's some references:
