If the disks are scsi the writes happen pretty much in parallel and you only read one copy when you read. It should only slow you down if you are using 2 ide drives on the same controller for the mirrors in which case you have to wait for one write to complete before the other starts.
They are SATA. My original thinking today was that performance would be better if I had 2 swap partitions: /dev/sda2, /dev/sdb2 set at the same priority so that *different* pages could be swapped simultaneously to/from the 2 drives. But as Matt pointed out, that would be less robust.
