I think that we need to tackle the absurd loss of performance that any
Windows HVM incurs with more than one processor. I have measured it and it
is amazing. I have an application that opens 15 independent network clients,
and with one single processor and the Standard PC Hal, it takes a little
over a minute to load the 15 clients and also to register with the SIP
provider. If I leave that unchanged, I mean "ceteris paribus" , and only
change the HAL to ACPI and add 8 processors, then the same operation takes
over 10 minutes. Hello!!! I am using the GPLVL drivers from James Harper.
Right now I am about to test the MPS -Non-ACPI HAL, but the driver still
create a BSOD. Maybe the problem is only ACPI, and not MPS, who knows. In
any case, what can we do so any Windows virtual machine can achieve a
"normal" performance, I mean, a linear performance when using more
processors and not this declining curve that can kill any host.
