    Hi ngockq , 

    Well , as long as this is not a HTTP Traffic, keep your eyes on Current connections on each pool member , not bits or Packets. 
    Bifgip loadbalances per TCP connection so that it's doesn't matter the size of this traffic on each connection. 

    So to make sure that your bigip loadbaance well and as expected , look at current connections.

Hi ngockq , 
it should be worked well , as Bigip loadbalance TCP connections not depending on packet sizes. 

Also take in your consideration HTTP1.1 Keep alive : which means same client who has an active connection through bigip will use the same flow or pool member ignoring loadbalancing as this client session still active in bigip connection table. 

These all factors may show you this stats on your pool.
