    I missed the beginning of this thread - how is the filesystem mounted?
For ext4, we finally found that it worked well... *if* it was mounted
nobarrier. That made the detar of a compressed tar file go from
literally 7 minutes to about 30-46 seconds.

That is interesting. I have barriers enabled, I will try disabling them (I have battery backup on the RAID controller, so it should be ok). Then again, I have barriers enabled on the other, very similar box too, and I hit 2GB/sec there, so I don't think that's the main factor. Still, will test. Thanks.
