VolumeDrive High I/O Wait

My pages take minutes to load on my VolumeDrive server. Is this really acceptable? I sent them an email a week ago and I never got a reply. About Tuesday the I/O wait started to go down, towards an acceptable amount.

Now a week later, every time a page is loaded on my VPS, the wait spikes to 99%.

If this continues and I don’t get an email back I may consider moving to another provider. I just recently found one on LowEndBox offering a great deal with the same performance as my VolumeDrive server for just about the same cost.

UPDATE 10/22/2012: I actually got an email back from VolumeDrive this morning, it’s a miracle! They said that the node required a reboot. (Sad face, I was trying to see how long my uptime could get…) Hopefully this reboot fixes up the poor performance. I’m a bit skeptical, but we’ll see.
