Sounds like a pretty cool way to test the throughput capabilities of your i/o chain.

Run a load that drives switching and observe elapsed times to archive per byte of non-compressed archive.
Double your multiplexing to the same place. Repeat the load and see if performance degrades.

If not, and if the rate of archiving is representative of production loads, you probably have plenty of headroom for archiving i/o.

Other than that, I'm not seeing it. Sort of like copying two copies of a file to the same tape.

Subject: Multiplexing archive logs to one disk

Is there any point multiplexing the archive logs to two different directories if both are on the same disk?

Thanks,
