EBS is still pretty poor for IOPS, even using SSDs. (It's network attached storage, after all). RDS also uses EBS instead of native DB replication, so expect a huge slowdown from native.
If you wanted real IO speed, run two postgres instances (in ec2) - in sync replication - using local SSD storage. I'd guess order(s) of magnitude more iops.
