That's right, we did talk about it when I first started using SmartOS and was playing with different raid configurations and what not and mainly learning. Since this time; I've mainly deployed Smartmachines, so I'd not seen any issues with the virto drivers and the synchronous write issues being discussed here. The Centos VM I'm working with now is the first time I've tried to deploy a kvm vm container like this in a high traffic production environment. Unfortunately, the disk speeds I'm getting now just aren't usable. If the management GUI is timing out, then the VM is pretty much useless. I can get better performance and no GUI time outs with an atom processor and 1G of RAM -- basically a couple hundred bucks in used hardware. I'm just trying to understand this and figure out what I need to do to get a useable performance out of SmartOS KVM. Are you saying that a SLOG device is going to solve the problem? Should I install 2 SLOG devices and strip them?
