HTTP traffic slow when access via LTM
I am trying to put together a POC to replace our ELB's in AWS with some f5 LTM's. Whilst i have been able to set up two VS's (one http->http the other https->http) i have found that the performance is significantly slower when using the f5 compared to the ELB. Changing profiles to Performance L4 on the http->http VS has netted some gains, but as this is ultimately meant to host an irule to redirect http to https this is not really useful. Further to this it does not help on the https VS. To give you an indication of the slow down, a ~20kb file takes over 7 seconds to transfer, 158ms of that is in the connection, the rest is receiving. To rule it out i have disabled all Irules and i am just trying to get a basic HTTPS offload to perform to an acceptable level, but i cant see that happening while http->http runs so slow.
