Ext App WaitQ piling up (781, 446, etc) indicates your "PHP suEXEC Max Conn" (http://www.litespeedtech.com/docs/we...pSuExecMaxConn) is not high enough to handle incoming PHP requests. increase to 50 (from 6) and see if alleviate the issue. But this should only affect the sites with non-zero WaitQ.

When all sites load slowly, check realtime stats and see if more sites have non-zero WaitQ. also run 'top -c' from command line and see other processes consume cpu cycles.
