reiser fs slow on mksf and mount

[Ming Zhang <mingz@ele.uri.edu>]

Hi, folks

I am not sure if this is normal or not.

I try to create&use a reiserfs on a 8 disk raid0. Then I found that mkfs
need ~90 sec and mount need ~70 seconds. 

Is there anything wrong on my side?

Thanks!

Guessing about desired format.. Kernel 2.6.11.12 is running.

Syncing..ok

Tell your friends to use a kernel based on 2.4.18 or later, and
especially not a
kernel based on 2.4.9, when you use reiserFS. Have fun.
