Hi !
Machine: PPro 200 MHz.
OS = FreeBSD 2.2-STABLE as of yesterday.
I just made some bonnie benchmarks on a fresh 2 GB filesystem.
The harddisk is a IBM DORS the controller a AHA 2940.
ahc0: target 0 Tagged Queuing Device
(ahc0:0:0): "IBM DORS-32160 WA6A" type 0 fixed SCSI 2
sd0(ahc0:0:0): Direct-Access 2063MB (4226725 512 byte sectors)
sd0(ahc0:0:0): with 6703 cyls, 5 heads, and an average 126 sectors/track

If I remember right, then I had about 5400 K/sec write performance
with former versions of the ahc driver. Now only the read performance
has the old speed of about 5.5 MB/sec.
Somebody else with similar results/experiences ?
