Profile change lag time?

Hello All,

 

 

I'm currently testing various performance capabilities with the F5 and our SAP Portal deployment. Unfortunately for me, this week our "F5 guy" is on vacation, so besides not being able to test the SAP Portal policy functionality, it's also difficult to run test cycles--when any [compression] changes I make don't seem to affect the behavior.

 

 

The past week I have been running test cycles of varying compression tweaks in the profile we have attached to the http:443 port. Specifically changing the content list types, etc.

 

 

What I frustratingly started to discover was there didn't seem to be a one-to-one correlation of changes through the F5 profile and results I was seeing through the browser. In short, it wasn't compressing what I thought it should have been, etc. In fact it wasn't compressing *anything* yesterday, when I had the threshold so low it should have been compressing ALL "compressable" traffic.

 

 

Oddly, this morning when I started testing again, it appears the compression is working for *some* things. Like it's healed itself. I haven't made any changes since last night, yet the results are different.

 

 

I've spent a fair amount of time trying to debug this issue and am at the point of thinking a) there's either a lag in seeing changes to the F5 profile or b) there's a bug in F5 microcode that is somehow affecting my results.

 

 

My question for the forum is: is there something I need to do beyond clicking [Update] after making the profile changes, or will the new settings automatically pick up? I looked in the logs last night and the system seems to send a kill -HUP to the process--my guess is it's forcing a restart.

 

 

Using the latest version:

 

BIG-IP 9.4.4 Build 73.1 Hotfix HF1

 

 

And I'm attaching a PDF of the compression config.

 

 

Thank you in advance.
