Hello Mohit.
There is no possible to fragment packets if you use a http profile.
When you assign a profile to a VS, F5 analyzes if this packet is RFC compliant and parses the whole set of app variables. This doesn't work at all if you divide those packets in several segments.
In your case, you should configure a L4 virtual using only tcp profile (no http).

Mohit_RatheeClient ------ Big F5 LTM ------ Server.
Client Send HTTP POST Request with HTTP body it gets Fragmented into two TCP segments ,BIG F5 LTM receives both the TCP segments ,BIG F5 forwards only one TCP segment and receives error from server that request doens't contain any HTTP body as TCP segment containing the HTTP body is never send to server and connection is reset due to this error.
Capture tcpdump at big F5 and wireshark at client side for the above conclusion.
Layer 4 performance and Layer 4 (HTTP) has no impact.
Can't figure what's wrong !!!!
Just for information POST request is a Microsoft active sync request...
