There was a standalone program which you can call from your recovery
script to prefetch the blocks needed to replay the next log file
before starting to apply it. I find this message but there may be a
more recent version if you search:

Otherwise I think there were some performance improvements to replay
but I don't recall which versions which improvements were in.
