Hi Folks, perhaps is it because of it that the L3 cache of the host on the guest does not arrive? root@x3850m2:~# dmidecode -t cache # dmidecode 2.11 SMBIOS 2.4 present. Handle 0x0043, DMI type 7, 19 bytes Cache Information Socket Designation: Internal L2 Cache Configuration: Enabled...

yesterday we made a test with Centos 6,4 and KVM, result better performance in the VM, but with CPU pinning Stephan

Hi Nachtfalke, i know this, but we are don't have a MSSQL server on this machine. Yesterday i running a test with 7zip benchmark, 1 Core = 2033MIPS | 4 Core = 7324MIPS ( 1927 MIPS per Core) | 16 Core = 6431MIPS ( 869 Mips per Core) Stephan

Hi Folks, today we have a test run with fewer ram, but no significantly modification of the cpu load, 12-14 user normal working 90-100% CPU Load without any io-wait. Someone has ideas in addition? Stephan

Hi Spirit, thanks for reply, this W2K8r2 Standard Server runs as a Terminal Server for 14-16 Users with MS Office 2010 & Addison http://www.addison.de (Tax Consulting Software) the DB-Server for this runs on a other VM @ the same Host. The DC for this runs on a other Host. Stephan

Hi Udo, the high cpu-load is in top of the host, without any io-wait (max 0,3%). I will try with fewer RAM and post the result. Possibly it is a problem with NUMA and/or CPU pinning, is there a possibility , similarly as under KVM@CentOS for set CPU pinning? Stephan

Hi Udo, thanks for reply! No, the disk @ NFS Storage is only for WindowsServerBackup, the Win2K8r2 run form the local storage. With only local storage is the same problem. Stephan

We test even different virtualisations solutions, also Proxmox 3.1, operation and options of this environment please us particularly well. On an IBM x3850M2 4X6 core Xeon 2,66GHz/96GB RAM 8 X 15KSAS we habe 3 VM's W2008r2, one is a Terminal Server for 16 Users, but the performance is however...
