Just as a follow up on this, I'm seeing a vast improvement in 10.2.1 between the performance of 'class search' versus 'findclass' for looking up a name and corresponding value in a datagroup. ie, the unit dies with 100% TMM CPU usage when using findclass. But it is under 35% average TMM CPU usage when searching all of the way through a 100,000 entry datagroup with 'class search'.

 

 

I would definitely recommend replacing findclass/matchclass with the corresponding class commands in 10.x iRules.
