Could you please check the number of dirty and writeback pages during a run with poor performance? See http://wiki.neo4j.org/content/Linux_Performance_Guide last part. I suspect this is due to Linux kernel writing out pages to disk when it should not (killing performance on the sequential writes to the log).
