best reiserfs mount options for generic benchmarking

[rwhron@earthlink.net]

I want to use a consistent set of "best" mount options
for various i/o benchmarks on reiserfs.  (bonnie++,
tiobench, dbench).

I've been using "noatime", and was thinking of adding
"notail".  tail packing helps on the bonnie++ "lots
of small files" test, but for most cases, "notail"
may be better.

alloc=preallocmin=4:preallocsize=9 was needed in 
2.4.20-pre2 to eliminate a tiobench regression when
thread count is high.  Is that needed in 2.4.20-pre7
and 2.5.34 and beyond?

Also, mke2fs has an option to create a larger journal.
For ext3, I create a 400MB journal.  (one of the tests
creates 256 (12888 / 256) MB files).  Is a non-default
journal size available/desireable for reiserfs?

Any other recommendations?
