From the (very little) work I've done with EC2, it seems that what you get
logically doesn't have much relation to what you get physically. I don't recall any guarentee that a virtual disk is equivilent to a physical spindle in terms of determining performance, or even that your virtual disk will perform consistently over time. Of course, you should test a few setups and see how they perform.

Hi,
I wanted to reply to an existing thread but it seems a new one has been created, so I think more details are required...

I want to run my postgres DB on Amazon EC2 using a EBS persistent disk for postgres installation. In this way data and pg_xlog will be on the same disk. I was just wondering if also on ec2 with EBS disks having pg_xlog on a different EBS disk could be useful.

Thanks in advance

 Do you think that it could useful mounting two different EBS to handle
 data and pg_xlog ?
