I currently have a system with 2x1TB WDC disks; it's now running 103 and I
hope to upgrade it to 108 or 109 shortly. Then we should be able to
measure between a build before and after 105.
It only uses around 200GB and it now takes around 1 hour to "scrub" it.
I have a nv_102 system with 2 mirrored 500GB data drives, 362GB used,
and that takes 12 hours to scrub.
My subjective impression is that back around build 70-something, it was
very much faster to scrub, but left the system almost completely
unusable whilst doing so. The impact of the scrub on the system
performance is now less disruptive. Usage of the system has changed over
this period, so it's difficult to be sure what's responsible for what
changes, but the increase in the scrub time certainly is significant.
The other thing that's changed over that period is that it grows 7 extra
snapshots/day, and now has 2700 snapshots - I don't know if number of
snapshots has any impact.
I would like to be able to pause and resume scrubs, so as to run them
only when system isn't being otherwise used. (RFE 6730306)
