Without knowing the exact requirements, it's hard to give an exact suggestion. You could try doing some simple load testing with the VIP configured with a single iRule and compare that performance with many small iRules. This should give you the most definitive answer for which approach is more efficient.

 

 

Administratively I think it would be simpler to combine similar functions into the same iRule. If you have a lot of rewrites to do, it would probably be more efficient to add them all to the same datagroup and use matchclass (v9 or 10)/findclass (v9 or 10)/class (v10) to determine which rewrite to perform compared with many small iRules.

 

 

Also, you can post questions like this to the iRules discussion group to get more relevant views on your post:
