I tested with the same environment and scenarios.
tested one scenarios for three times and compute the average for more

Thanks, Amos

1 - avg-old.netperf.exhost_guest.txt
2 - avg-fixed.netperf.exhost_guest.txt
The output is word wrapped and generally unreadable. Any chance you can
provide us with a summary of the outcome ?
Cheers,
Ben.
Hi Ben,
The change of TCP_RR Throughput is very small.
external host -> guest: Some of throughput of TCP_STREAM and TCP_MAERTS
reduced a little.
local host -> guest: Some of throughput of TCP_STREAM and TCP_MAERTS
increased a little.
About compare result format:
---------------------------
1 - avg-old.netperf.exhost_guest.txt
average result (tested 3 times) file of test 1
2 - avg-fixed.netperf.exhost_guest.txt
average result file of test 2
======

#rx-pkts: received packets number
#rx-byts: received bytes number
#rx-intr: interrupt number for receive
#io_exit: io exit number
#irq_inj: injected irq number
Thanks, Amos.
