(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? -- Randy Hron http://home.earthlink.net/~rwhron/kernel/bigbox.html
