Subject: How long will a shrinkfs take?

Hi
I have a 1Tb reiserfs that I want to shrink to 500Gb
400Gb of data is used.
Any estimates as to how long this will take?
Sustained I/O is about 33Mb/s at the fs level, 44 Mb/s at the lv level
and 65Mb/s at the md0 level.
(I didn't expect the fs to be so slow so I'm going to try a few tuning
params on the new 500Gb space before copying over the data and growing
back to a Tb)
Is it proportional to the amount of shrinkage (ie 2 hrs to reduce by
50G, 20 hrs to reduce by 500Gb)
David
