Hello,
I am using kvm83 on Centos 5.2
I did some iperf test on my kvm guest and I got the following results
over a 1GB connection:
~650Mbit/s inbound
~250Mbit/s outbound
that is performance appears to be asymmetric.
Is this normal ?
The inbound data flow is quite impressive as performance but the
outbound is poorer.
How come this happens ?
I di dtest on the bare machine ad it is around 800Mbit/s inbound and
outbound.
any hints ?
thank you
Rick
