Hi Sascha,

 

 

in my basic test, I have seen cpu cycle reduced. what I did was putting partial of your iRule and mine in RULE_INIT (of separate iRule) and compare cpucycle reported.

 

If you still see that cpucycle is very high. Maybe I was missing something. can you post your tested iRule?

 

May I ask what hardware/software are you using? (I tested on 6800/v10HF1 and 3600/v9.4.6)

 

 

btw, in production irule, you may remove unnecessary log (or consolidate them by saving all information in variable first then issue log command at the end). I guess you may already did this. (so just in case)
