Perfomance gain of using HTTP Classes over iRules

Hi,     I raised this issue in the general iRule forum (http://devcentral.f5.com/Default.aspx?tabid=53&forumid=5&postid=33291&view=topic), but I thought this would be the best place to focu...

[b]I would be surprised if only 1000 conns/sec put any real stress on the LTM.[/b]

 

 

Any tips on how I could generate more load? Do you have a prefered testing tool?

 

 

[b]Did you actually enable timing in the iRule and view the stats after the test had completed?[/b]

 

 

I did. Results are:

 

Current iRule: % CPU utilization / request: 0.026238047%

 

Stripped down iRule utilizing dataclasses: % CPU utilization / request: 0.016391819%

 

Some notable difference. Do you think i would get a wider gap if i was to generate more load?

 

 

[b]I think Naman was hoping to get details on what kind of performance improvements he might expect if he was replacing an iRule with HTTP classes. Has any performance testing been done to compare an iRule and a set of HTTP classes?[/b]

 

 

That's right Aaron.
