Hammer performance

[Michael Neumann]

Hi,

Just compared writing a 1 GB large file with Hammer and got:

  dragnas# dd if=/dev/zero of=test count=2000000
  2000000+0 records in
  2000000+0 records out
  1024000000 bytes transferred in 26.880290 secs (38094827 bytes/sec)
When I do the same (on the same hard disk) with UFS, I get around twice
the write performance:
  dd if=/dev/zero of=test count=2000000
  2000000+0 records in
  2000000+0 records out
  1024000000 bytes transferred in 12.816585 secs (79896477 bytes/sec)
Is there a possibility to tune hammer in any way, for example by giving
it more memory?
Regards,

  Michael
