vBSEO Load Problem

On version vBulletin 3.6.x and vBSEO 3.1.0 server was attributed too muuch... We've installed xcache to server and server was attributed more... We'moved stronger server and upgrade to version 3.7.0 - 3.2.0 RC5. And now server's attributing much more and cpu load is %40... We upgraded to vbulletin 3.7.1 and cpu load did not dropped. As you know we're using RC versions of vBSEO.. According to it there're too many changeable things.. And we wonder when the full version complated, the cpu load problem will be filxed? Either whats the problem? If the cpu load never dropped and if it contiune to increase we must disable vBSEO.

What is your server details also what is your online user number with 15 minute cookie timeout.
