Re: Quick questions about f5's iRules

In my past observations as a QA Engineer for the F5 products in our
organization. We only noticed a slight degradation in performance using
iRules, in milliseconds or fractions thereof. This is said with a
caveat. The more complex the iRule the more degradation it gives. Using
RegEx in an irule dogs it down horribly.  Unfortunately I can't send you
any data as it's internally confidential.

		Hello Load-balancing Gurus,
		
		I have simple questions about f5's iRules. Please share
your experience if you have anything :-)
		
		1) f5's iRule can impact their L4/L7 performance? it
means if we're turning on the options, there is
		   any performance degradation or improvement?(maybe upt
to iRule script)
		2) If there is any official marketing data in regards of
iRule test, where can I get? (like Tolly group
		    report).
		
		Thanks in advance.
		
		Best regards,
