Thanks for info. Are your sure timing on is necessary on 11.5+? I have no timing on enabled on events in my iRule and can see stats when using show ltm rule rule_name. Do you know by chance F5DevCentral_iRulesRuntimeCalculator.xls tool provided in this article?

 

Is this tool still useful for rough evaluation?

 

When I entered data from my iRule (setting CPU to 2000 000 000 - I assume it's correct for my VE reporting "cpu MHz : 2000.000" from cat /proc/cpuinfo) result in last table "Max number of requests" for average is around 561. I assume that it means max connections/s that can be handled per CPU?
