[Spread-users] Maximum message rate achieved is only 6600 msgs/sec (for message size 1300 bytes)

[Sandesh Kumar Sodhi]

Hi,

I was doing the performance testing of GCS Daemon.
The maximum message rate that I am able to achieve is
around 6600 messages per second. My message size is 1300 bytes.
Could you please let me know if this is the maximum that we 
can achieve. Please do let me know if performance parameter can be tweeaked
for GCS
to improve performance.

If this is the maximum rate that can be achieved for the message size than
we shall have to remove the use of GCS from our platform.

GCS version I ma using is: 3.16.0
Message Type UNRELIABLE_MESS
Message size 1300 bytes
