The dbench data is available in these directories:
2.4.17-ext2patch 
2.4.17-vanilla

There are 6 lockstat files in each directory.  The .[0-9] after the file
indicates how dbench was run.  
dbench.lockstat.1 means: "dbench 1"

These are from only a dual-cpu machine, so the data don't change much
after 3.
