CirrusHi,
You have several part that can cause latency : regexp, http payload collection, string manipulation.
You can try disabling each one at the time to check which part of your irule can cause latency.
Try removing the HTTP::collect and HTTP_RESPONSE_DATA to start. I think that it may be your issue.
goldi_247196thanks, for the quick answer and we will use the timing command. also we are aware of the regexp and we plan to move the "txId" to the headers. but if I'm not mistaken we are experiencing the latency after the regexp command has been completed and more accurately the latency is being viewed when executing the "persist uie" command. does this make sense...?- Yann_DesmarestI never had see any latency on universal persistence. But basically, I assume that extra long string used as persistence records along with big connection table may impact performance.
