Last week I setup two Windows 2003 32bit (one of them is cloned from
the other), GPLPV, 2 CPUs each, with ACPI=1 on domU config. iperf got
around 500 Mbps.
Then out of curiosity, I changed one of them to have one CPU, ACPI=0,
and changed Windows HAL to Standard PC. iperf now gives me a whopping
1.4 Gbps.
Both tests where done without messing with any network offload
settings. Is it safe to assume that, for now, Standard PC HAL will
give better network performance compared to ACPI HAL when used with
GPLPV? Is it also the same case for the disk driver?
