Remember that the penalty is on writes, i.e. pageouts. For massive pageouts you should already have robust paging configuration to handle the burst, if mirrored it might have to be a little more robust. Normal performance is more depedent on page-in response times and they are not influenced by mirroring. One reason to mirror pagevolumes is to keep the configuration simple: mirror everything, so you are sure you will never forget a volume.
