[omniORB] GIOP doesn't handle the flow well if the latency
increases to WAN speeds.

HI All,
We have a application uses the GIOP protocol, a layer 7 protocol (same
level as HTTP) to transport data over the network. It seems that the
GIOP protocol has a fragmentation process as well, just as TCP. However,
GIOP doesn't handle the flow well if the latency increases to WAN
speeds.
Does the solution is to change the harder coded buffer size ?
See example of trace of our application :
