Hi All!
My FreeNAS performance is really bad.
Perhaps a big part of it is due to incorrect tuning.
However I've gone through a lot of values of many commonly tuned loaders and still didn't get good results.
I thought that the following issue might have a say in the performance too, or perhaps it might turn out to be a part of a bigger issue...
My Spec:
FreeNAS 8.0.3 RC3 x86 (32bit).
P4 2.8 GHz
4GB ram
4 identical WD HDDs - WD20EARS - SATA 3 Gb/s
Mobo: MSI 945GCM5 with Intel ICH7 chipset with on-board SATA controller that is supposed to allow 300MB/s transfer speeds.
I've looked through all the possible BIOS settings and didn't find anything relevant (could I have missed something?)
Here's my the relevant part of syslog:

Does anyone have an idea of why the drives do not work at 300MB/s as they are supposed to?
Cheers!
