TCP Tuning: How to test web application performance
Hey everyone... new guy here! I know this is very basic, but it'll be hugely helpful to me.
We have a web application that we use heavily, but has been having major performance issues....

Vic: do you all suspect that the LTM is the culprit here or are you just trying to help matters by tuning it? This is actually a pretty big question.
If you're seeking end-to-end clarity on possible performance issues, one thing I'd look at is pointing an Extrahop device at this environment from a spanned port that can see all sides of the transactions (all the way back to the DB if possible). They do an incredible job at identifying bottlenecks and performance issues, as well as giving some guidance on how to rectify such issues from an application delivery perspective.
Another thing that I would do is use HTTPWatch to look at the HTTP transactions carefully - it'll show you round trip times, network times, etc. which is extremely handy.
