one website loads very fast other very slow

Ext App WaitQ piling up (781, 446, etc) indicates your "PHP suEXEC Max Conn" (http://www.litespeedtech.com/docs/webserver/config/general/#phpSuExecMaxConn) 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.

looks like having been improved by looking at the graph.
one busy site still have the problem(WaitQ=498).
try to enable anti-ddos feature, see if can resolve the issue.
especially
Server --> Security --> Per Client Throttling --> Dynamic Requests/second, tune it to 5,10,... to see if any difference.

That vhost (with WaitQ=498) isn't busy. However, it takes a long time (somewhere ~20-30 seconds) to complete the php request (even the incoming is only 5 requests/sec). Hence WaitQ pile up. You need to check the script and see why it takes long time to complete. Thing like the script pull resource from external site, etc.
