siis/atacam/ata/gmirror 8.0-BETA3 disk performance

From: Derek (freebsd lists) <"Derek>

Hi,

I've been testing the new siis driver, and I have found no
appreciable performance change, using dd as a measure of "raw"
performance.

I get about 40MB/s read, and 30MB/s write.  See attached
bench-*.txt files.

Am I expecting too much, or do I have something else going on
here?  (e.g. dd being a terrible benchmark of disk i/o)

Is anyone else seeing better/worse/same numbers?

Also I find it surprising that my gmirror read is only 40MB/s,
and not 60-80MB/s, any thoughts on this?

Thanks!
- Derek
