Slowing Upload my application http behind F5 Big IP

Hi,

 

Please I need your help, my application contains one area upload the small files, size between 200k and 600k. When we acessed behind F5 Big IP vip , upload area is slowing, but direct access in webserver application (backend) this area upload is more fast.

 

I changed configuration the tcp profile but not function for me =/

 

Was disabled Nagle Algorithm, Bandwidth Delay, Slow start and Limited Transmit Recovery.

 

My BigIP is in version BIG-IP 9.4.5 Build 1086.1 Hotfix HF2.

 

Thank's for any help.

    Hi Nullck, There various reason why this could be slow. Can you post your vip and profile settings associated. Perhaps someone in the forumn can spot a setting which maybe slowing you down.

     

    I hope this helps
