HyperV HDD Performance in host very slow

-

i've been happily running hyperv on windows server 2008 & 2008 r2 last couple of years. servers big pcs, nothing special.

i've taken mobo used hyperv server, , installed windows 8 on it. has 16gb ram & 3.1 ghz quad core quite capable of running 3 or 4 vms. doing windows 2008.

i've added hyperv role windows 8, , hdd performance on host grinds halt when more 1 vm running. disk average throughput measured hd tune pro drops 135mb no vm, 44mb 1, way down 0.7 mb 4.

disk access time drops 15.3ms 23.8, 606.8 ms.

my new 'server' running same hdd , not show similar drop in performance. it's happily running 6vms.

i think leaves 2 possible problems: either hdd starting fail, or hyperv in windows 8 doesn't work in server 2008 r2.

any thoughts? time replace hdd?

thanks

still talking myself! i've decided split vms across 2hdds now, without using raid. hopefully, windows 8 have updates improve things shortly.

failing that, i'll have go windows server 2012.
