I just installed mpm_worker for Apache and added this to pre_main_global.conf:<IfModule worker.c>ServerLimit          40StartServers          2MaxClients          1000MinSpareThreads      20MaxSpareThreads      50ThreadsPerChild      25MaxRequestsPerChild   0</IfModule>To test to see if this actually works, I changed the variable and restarted Apache.<IfModule worker.c>ServerLimit           1StartServers          1MaxClients            1MinSpareThreads       1MaxSpareThreads       1ThreadsPerChild       1MaxRequestsPerChild   1</IfModule>To my surprise my busy site still responds as normal. I tested this on multiple browsers and deleted all the cache. What did I do wrong? 
Installing mpm_worker for Apache and configuring pre_main_global.conf doesn't seem to work
