Aug 01, 2014irules could be CPU intensive depending on commands you are using. Subtables could impact performances.
Could you check with show ltm virtual if cmp is still enable on your vs?
the following line set client_id [format "%08d" [expr { int(1000000000 * rand()) }]] is requiring resources outside of tmm and cost a lot, even more as you are doing it per request.
if you want to count sessions you should move you logic outside http_request to TCP events, but in this case no more cookie usage.
could you describe a little bit what you are trying to achieve ?
