Test the disk I/O of your VPS

so you are using the onboard raid? that normally does not work in linux..
I'm not sure what to look for. I don't find something related to disk information?
That's what they deliver to me. It got me errors like below. I am considering to reinstall by myself and use mdadm, but for its current purpose I think it's okay.
Not only that, but each of those use a different amount of ram centos is the most hungry as we all know less ram less performance in dd, so please, try with the new RAM I gave you.
Sorry you can try,
dmesg | grep -i scsi@earl relevant info only, confirming smartctl output.
nice they gave you all the same drive.. the server is pretty nice too.. with AMD cpu you can do nested vm's, and the 1045 supports RVI so techinically u can install kvm inside a nested proxmox.
Thanks, nice new commands for this newbie's notes. For now it's running OpenVZ, mostly for experimental. I planned to try proxmox, but recent news about Feathur being cheap/free with no upfront cost somehow interest me more.

the great thing about proxmox is the ready made OVZ turnkey templates.. probably over 100 template like, wordpress, LAMP even vanilla forum, etc..
you should install it, you won't regret it..
That's really fast...

Hum strange. Centos is the most memory hungry but should have had enough of it, yet is still the slowest.
Since it is xen, it will be slower than ovz but not that slower, I think this is something about the CentOS kernel.
Nice! How about LA node?

i3D.net - HP DL120 dedicated server, single 1TB disk.
Iniz - 4 Netherlands OpenVZ, separate nodes.
Gee, that 1 tb disk is really slow unless you are using it for other things too.
