CONFIG_HIGHIO and CONFIG_2GB improved dbench throughput on ext2, ext3, and reiserfs. I compared 4 2.4.19-pre9-aa2 kernel configs on a quad Xeon with 3.75 GB ram.
dbench 192 improved more than dbench 64. ext3 improved 35-65% with these options. ext2 improved 27-35%. reiserfs improved 17-30%.
dbench summary is at: http://home.earthlink.net/~rwhron/kernel/123gb.html
For sequential reads, HIGHIO and 2GB tiobench has increased throughput and lower cpu utilization. tiobench sequential write performance in some cases is lower.
