CirrusF5 LTM VIP performance Issue
Hey All
I have ltm vip setup on my f5 running 11.6.1 which is reported to have slow performance issues. The vip is for the url abc.xyz.com which is hosted internal to our organization. The users are from different locations. The users are complaining slowness when accessing different components on the url.
the vip is configured for port 80 and 443. VIP on port 80 redirects to vip on 443 through irule. There are no client & server ssl profiles on vip with port 443.
Please advise of the things that needed to be verified.

If you do not want to use SSL offloading, there are only a few things you can do. One of these is to use tcp-wan-optimized profile for client-side TCP, then tcp-lan-optimized for server-side TCP

Hi AnandB,
the only source of your problem is TCP profile (Be sure that the profile that you use have Nagle's Algorithm Disable). I already had a problem that caused latencies because this algo.
Next point can you check in interface side (stat) that you don't have any error:

David__PaschDid you try Youssef's suggestion of disabling Nagle's? That behavior sounds like the F5 is buffering for some reason.
