2xXeon E5540 vs Phenom II X6. I don't understand result.

[Deni74]

qcow or raw vm 2003x64 server with SQL 2005 standart.

1. 2xXeon E5540, Supermicro X8DT3, 36Gb ECC, 12*137Gb Seagate SAS Raid 10 (~220-300 mb/s).
2. Phenom II X6 1055T, basic Gigabyte MB, 16Gb ddr3, Kingston SSD (~80-120 mb/s)

balloon: 0
boot: c
bootdisk: ide0
cores: 4 ( -6 -8 no difference)
ide0: local:200/vm-200-disk-1.qcow2 (or .raw no difference)
localtime: 1
memory: 8192 ( -16 Gb no difference)
name: mis
net0: e1000=1E:67:48:0A:91:CB,bridge=vmbr0
ostype: wxp
sockets: 1 (or 2 for Xeon - no difference)

VM work faster on Phenom with any settings (memory, cores, sockets), why?
Using memory ~3-4 Gb. Cores 4, 6 or 8 - no difference.
But default CPU loading Xeon - 10-12%, Phenom - 4-5%.
Programm start faster about 4-5 secs on Phenom.



May be.. I need make some settings for real use 2 physical CPU in vm? (SMP) except the web interface?

Xeon E5540 - 4x 2.53Ghz CPU
Phenom II x6 1055T - 6x 2.80Ghz

AMD has more L2 cache, and is a newer CPU...

I forget CPUBOSS. Yes, i think u r right. But anyway single 6 core cpu vs 2*4 core. Geekbench 8,085 vs 9,386 per socket.

 

[hotwired007]

but you're only comparing 4 cores from each CPU - even if you config 2sx2c or 1sx4c in your VM, its still only 4 physical CPU cores in use, thats a whole 1.2Ghz difference for the AMD vs Intel... and thats on the AMD base speed NOT the 'turbo' boost CPU

 

[Deni74]

1.Supermicro X8DT3 - 2 sockets MB with 2 physycal cpu - 8 core.
Settings: cores: 4 sockets: 2 = 8 phys core
2.Gygabyte - 1 phys socket with 6 core Phenom
Settings: cores: 4 sockets: 1 = 4 phys core

Phenom results better anyway. I comparing all cores each CPU.

Hi,
and if you use the FX8350 your speed raised again .

I have two nodes with that processor (with 32GB ECC-Ram) which work very good.

Hi Udo,

i am thinking of testing FX8350 also in our labs, 32 GB ECC ram sounds also great.
can you recommend a part list? (especially mainboard and ram)

thanks!

 

[Deni74]

transfer vms to other proxmoxs to safe.m ake clear windows with sql server, install soft with same options. xeon - winner. everything sql requests more quckly 80/20%. Testing 8350 interesting for me too.

Hi Tom,
sorry for delay - I was bicycling in sweden.

As motherboard I use Asus SABERTOOTH 990FX (MIL-Standard)
and as ram Kingston KVR13E9/8HM (some distributor call the ram "8GB Kingston ValueRAM Hynix DDR3-1333 ECC DIMM CL9 Single").
For this board is also an graphic-card necessary - I took a "512MB PowerColor Radeon HD 5450 Silent Passiv PCIe x1" because of the use of only PCIe x1.

Except of CPU/Mainboard/Graphiccard are all server-components

Many thanks for the hw list.
