[SOLVED] very low benchmarks on 2008r2@PVE 5.1

[MythOfTheLight]

Try PVE 5.1 instead of Microsoft Hyper-V Server 2012 on old server:

2x Intel Xeon E5335 @ 2 GHz, 16 GB DDR2-667 ECC FBDIMM (4x4gb), 2x 1TB HDD

1. PVE installs, and work (looks normal)
2. Create VM and install Windows Server 2008 R2 by wiki
3. Bench 1 core perfomance 7zip - 1955 points on 2008r2@PVE and 1949 points on 2008r2@hyper-v - looks everything is OK.
4. Bench 8 core perfomance 7 zip - 4643 points 4.4 mb packing 57.6mb unpacking on PVE, but on hyper-v 13264 points 10.8mb packing 164.4mb unpacking, and 13894 when os installed on server directly.

All virtualisation tehnologies enabled, but something wrong with PVE 5.1? Or I should try PVE 4.4 on so old server?

tested with PVE 4.4 - same result... Looks like freeware Microsoft Hyper-V Server 2012 is best for windows...

which benchmark program do you use ?

 

[MythOfTheLight]

7-zip.com gui has a multithread compress/decompress benchmark

this only reflect cpu and ram bit no disk i/0 ..... i get these results BAREMETAL. PROXMOX vm.

1 had these results for 8/8 cores

baremetal: 13894 hyper-v:13264 proxmox 5.1 & 4.4: ~4600

also today i run 8 copies of vm with 1 core and run test. All 8 VM at a time give me full result of 1 core:

baremetal 1 core: 1980
proxmox 5.1 & 4.4 1 core and 1 VM: 1950
proxmox 5.1 & 4.4 1 core and 8 VM at a time: 1900

now i'm installing PVE 5.1 on two another servers, with Xeon E3-1220 v3 and Intel G4560 =) (storage server, take for testing...)
i think all problems just because Xeon e5335 too old. But it works correct in Hyper-V as host and Windows as guest.

Looks that Xeon E5335 / E5440 too old and not good idea for virtualisation on proxmox. Tested E3-1220 and G4560 - perfomance 98-99% of baremetal
