VERY High Pages/s on Hyper-V

have started working new organisation.

have hyper-v server (hp proliant dl580 g7, 4x10 core cpus, 128 gb ram) running few guest servers little, 1 of them primary sccm 2012 server (32gb allocated), , performance poor.

added wsus server, , performance noticeably worse.

performance monitor has shown me pages/s peaking @ 16,500, average of 250!

since doubled ram last night , set sql use between 16-24gb ram.

can confirm if pages/s indicative of insufficient ram, many articles have read state?

there sufficient capacity on hyper-v double ram on sccm guest, means downtime , changes submitting.

available memory static, holding @ above 12 gb free, no correlation pages/s spikes,

cpu 40% average, min 16% min, 76% max - little high say, , host has 40 cores, , guest 6, looking @ upping them, again requires planned downtime.

guest quite loaded distribution point sccm. i appreciate advice on network counters should monitored.

else can check/change?

hi mikhailcompo,

could please try shutdown vm then disable numa spanning in hyper-v settings (to apply change may need restart host).

after in vm settings navigate processor --> numa  click "use hardware topology" , may see number of "maximum amount of memory " , "maximum number of processors" please allocate memory , vcpus  not large number  that vm .

then start vm , check result .

best regards
