Thanks for the clarifications. At this point there are only a handful of VS out of 200+ VS's that use an irule exercising an increment/reset gvar. Worst case scenario, with no modification, those particular VS will just run on the first core of the LTM in cmp demoted mode. Since the total LTM cpu utilization is still well below 40% utilization its probably something that can be postponed until things start heating up. It is comforting to know that there is a close to dropin replacement for an "incr ::gvar" with "table incr" just have to take the time to retrofit based on that
Cheers
