Http file download is 50% slower through f5 than direct to apache server

First off thanks so much for the quick reply. I did get captures the other day and was looking for anything that jumped out to me but didn't find anything but then again I must admit I am not a wireshark expert. So any pointers on what I could look for in the captures? I will try switching the profiles around like you suggested, that makes sense. One thing I was thinking is could an MTU mismatch or chunking mismatch of some sort cause this? anyway thanks again.
