Hello all,
So would I be correct in concluding that I am CPU bound at this point? My
machine is busy creating the parity information so can not receive any
faster. A CPU replacement is in order but I have one question in that
direction. It appears that the md0 process is only using one core. Is
this because it is a single file being written? Should it be using both?
The main thrust of this question is which type of CPU upgrade will help my
situation. I could go for a faster MHz or more cores. Actually, I can't
go much faster on the MHz front. I think 3.4GHz is max and I'm at 3.0GHz.
As always, thank you for all your advice.
