Re: Bad RAID1 read performance

As you suggested with two threads I get 42.39 Mb/s in one and 40.70 Mb/s in
the other one, so that's more than 80Mb/s. That's what I expected with a
single thread, so thanks for the information. It seems I will have to buy
better hard drives if I want increased performance...
