troubleshooting slow performance
folks
i'm getting poor performance for my proxy environment and i'm hoping you can help
i have an ltm 1600 (11.4.1) cluster in front of 3 ironports (C670s) but performance is poor when more and more users start to use the service
in the morning and late afternoon things are very good but the rest of the day browsing is very poor
if i check the ltm with the show ltm persistence persistence-records things run well up to 3000 records, after that a web page can take 30 secs to load
i'm using a http amd https profile with a different vip for each one, there is no decryption taking place and a simple irule to log
the ltm shows 60% utilisation on the ltm and 18% on the ironport
can anyone give an indication of how to properly troubleshoot the ltm to make sure its not the cause of poor performance
thanks
