I am trying to setup mysql on XEN. I need to set it up on NFS so I can migrate the domain when needed. I am getting unexpected results and wanted to get some feedback. Here is my setup:
Dual 2.0 Ghz AMD Opteron 2GB of RAM Broadcom GB NIC Standard Fedora Core 3 (FC3) Mysql w/tpc-c medium databases on the NFS share XenU filesystem on the NFS share
Dual 2.0 Ghz AMD Opteron 2GB of RAM Broadcom GB NIC FC3 w/XEN kernel patch Dom0 = 512MB RAM DomU = 512MB RAM
PIII 2.0 Ghz 512 MB RAM Standard Fedora Core 2 TCP-C client Results using the tpc-c benchmark: Baseline ~3300 new-ops per second Machine 2 booted to the standard FC3 Xen0 ~ 1700 new-ops per second Machine 2 booted to Xen kernel with 512MB of RAM XenU ~500 new ops per second Machine 2 booted to Xen kernel with 512MB of RAM DomU booted from NFS share with 512MB of RAM Am I missing something here or is that much degradation expected when booting a virtual machine over NFS. __________________________________________________ |
