I recently bought a VPS and am in contact with their support about this issue, but I would also like to get an expert opinion from here.
It's a fully updated Windows Server 2008 R2 VPS hosted on VmWare ESXi 5.
In order to test the disk speed on the VPS I have tried copying large files around on the different partitions. I am getting speeds of around 30Mb/s between them which I think is decent, however when I'm copying files the CPU is also being hit hard across all 4 cores with the System process accounting for about 50% of it. When the copying stops the CPU goes back to 0% load.
This might be a duplicate of this thread, maybe its the same problem here?
It's just weird that the server is at 0-1% when I'm not copying and holding at 40-80% when I copy. If it's the same as in the other thread I linked, it sounds like I should have a constant high load.
What could be the cause of this, and what should I ask the provider to do/ test?
