Re: Sync rates?

My machine was idle during the rebuild.  When I say idle, I mean no one
logged in, no user processes running (except me sshed into the box), no
database, no I/O other than the rebuild.

While the rebuild was going on my system was debilitated, totally slow to
respond to ssh commands
