Re: reiser4 performance

[Pat Double <pat@patdouble.com>]

Actually I did make it public, hit the wrong command on my mail client ;)

I did not try the -mm kernel (latest patches is for -mm5 IIRC), I use software 
suspend 2 and it does not apply to the 2.6.12.x-mm series. Except for this 
problem reiser4 has worked great for me. Since I use a single partition and 
'/' does not get modified much I copied all my data over, rebuilt the 
filesystem, and then started using it. I have not discovered any problems, 
and the filesystem is quite fast.
