Bonnie is a simple benchmark which measures how fast it can read and write to a filesystem. These are the results of bonnie runs that I've made on various machines.


Generic P133 64MB RAM, two HP 97560 (very old 5 1/4" full-height 1GB drives) on Adaptec ISA controller:

two-disk stripe on Adaptec 2940 PCI controller (with kernel compile on another disk). Compare this to the "8k stripe" result above.

Looks like the PCI controller is a win!

Something's not right - these numbers suck!

OK, managed to get dma enabled (don't know why I have to use hdparm) and now things look a little better:

I'm still surprised as hell that the VAIO smokes this machine in so many categories. I guess it does have a lot more CPU than this machine does, but I wouldn't expect that to matter for block I/O. Go figure. (I found out later that the DMA support was unreliable so it would cause an error somewhere during the test and the kernel would turn DMA off)

P2 266 96MB, Western Digital Caviar 4.3GB as a slave on the same bus as the 15GB maxtor above:

UDMA comes up enabled by default with this drive; seems to use very little CPU. I think that something's wrong with the DMA support on the maxtor drive.

P2 266 96MB, Western Digital Caviar 30GM 7200RPM as a slave on the same bus as the 15GB maxtor above:

              -------Sequential Output-------- ---Sequential Input-- --Random--

not bad, although not a huge improvement over the 15GB drive. (Again, DMA was getting turned off during the run)

My spiffy new AMD Athlon 1.2GHz machine:

The VAIO still rules, guess I've got to look into DMA issues (yet again). OK, here are the results after hdparm -d 1 /dev/hda :

A new king of the hill, by a longshot. DMA is your friend.

An upgraded "poohpa", PII-450, 128MB PC-133 RAM, Western Digital Caviar 30GB 7200RPM, dma enabled:

              -------Sequential Output-------- ---Sequential Input-- --Random--

Yup, that's the stuff. Another nice feature of this drive is that it is quiet.

At Black Ink Systems I have a Dell Precision 220 (PIII/933, 768MB RAM, WDC WD200BB-75AUA1 disk)running Red Hat 7.2 (kernel 2.4.9-13):

I've also got an IBM ThinkPad A30 laptop. Big 'n' ugly:

During the Black Ink restructuring I had a VA Linux 1220 1U server in the basement. It's a 2xPIII-933 with 2GB RAM, and only one Quantum Fireball LM20.5 IDE disk.

I think that these results are bogus because the machine has too much memory - it has 2GB memory, and that's the largest file that you can write with a 32-bit filesystem. The input numbers look out of whack - probably because it's not reading the disk most of the time.

Here's an upgraded (again!) poohpa, this time a PIII/933 with 512MB memory. Same disk, i.e. Western Digital Caviar 30GB 7200RPM:

Phoenix is a Compaq DL-380 dual P3/1000 with 4 18GB SCSI3 15000RPM disks and a RAID controller. The machine has mucho RAM but I booted it with 356MB to make the test more reasonable. The RAID doesn't have write-back cache. A 3-disk stripe runs at:
