fastcgi_max_temp_file_size 0;
This directive turns off fastcgi buffering according to the source code.
i did this, and the buffer errors are gone. however, the pages load very
very slow. take about 5-10 seconds to load the page.
could it be my php-fpm.conf ?
the thing is why i am going nuts about this is because the same exact
config (same nginx/php-fpm), i am running on a centos server, and i am
able to push over 200 mb/s and everything works perfectly fine.
i switched over to freebsd to squeeze some more performance out of the
server though.
also i have noticed that when more and more connections are established
to the server, my php-cgi processes are frozen in “sbwait” state:
