I'm running a Mac Mini Server 2.66ghz C2D, 8GB Ram OSX 10.6 Server.
I'm running a WordPress 3.1.1 install with Apache/PHP/MySQL, only serving the pages (images come from S3) per page size is 19k. When I run AB I max out @115k and 6 requests per second. It's straight across the board solid numbers. Now I know my server can handle more and I have 5megs upload so I should really be maxing out somewhere much higher.
Any ideas of where I should look first? I'm sure it must be a setting in Apache/MySQL/PHP that's limiting the server. I'm on more or less on a stock httpd/php.ini except compression is enabled, fast_cgi and mod_rewrite for WordPress.
ab -n 1000 -kc 200 127.0.0.1
No issues. completes the test in a few seconds. It craps out at
-n 1000 -kc 500 .. but you would expect that.
Could it be my gateway is throttling the connection and that's why it's a solid 115kpbs upload?
