I am load testing a worpress site with loader.io , i am sending 100 concurrent requests per second, running the test in exactly 1 minute. The test fails considerably after 20 seconds or so, nothing logged on the apache error log,
I monitored ram during the test and ram seems to be fine, the server is not running out of ram.
Load average however shoots to 3.55 ,
am using apache event mpm , below are my settings
<IfModule mpm_event_module>
ServerLimit 550
StartServers 10
MinSpareThreads 75
MaxSpareThreads 250
ThreadLimit 64
ThreadsPerChild 32
MaxRequestWorkers 550
MaxConnectionsPerChild 0
</IfModule>
