Hi,
I have tested the dist-gem5 using the example booting script, which issue a
ping command to test the network connectivity. However, I have noticed that the
latency for the ping command is extremely high, as 993ms.
Is there any way to shorten this latency or is there anything wrong with the
settings?
Thanks.
