Performance and CPU load 7 years 5 months ago #1012

hello,

I'm doing some test using 2 twin server (Dell Poweredge SC1435) with 2 opteron quad core (8 core in total) 2.3/2.7Mhz and a local SSD + 1 mecanical HD

I've seen that storage performance, on master, are 25% slower with HA-Lizard then for normal single xen server, I also seen that when i write on disk 4 (crystal disk test on a Windows VM) CPU-cores go from 40 to 65% of load.

It's normally or it's because the server it's not enought powerfull ?

Thank you in advance for info

Testing done in our development environment shows negligible difference in storage performance of VMs running on the master.

IN our case we use HW RAID with 10K SAS disks in RAID 1.
WE have not experienced any CPU spikes.

All HW environments will perform differently so cannot really comment other than our own test results.
