Why do you post to -net & -bugs, these are not the right lists for this kind of questions. stable or questions is better, and please don't cross-post. > At first we started installing FreeBSD5.4-RELEASE AMD64 LSI Megaraid was > detected and raid was running in optimal.

Which I searched online for with no clues. This is probably harmless, I've never had any problems with it. > Anyways went to system installation it starts installing bursting to 2600KB/s > and after 55% it goes down to 800KB/s than when reaching ports it goes down to > 33KB/s and this is CDROM installation!! The ports are lots of small files it takes time to write these to disk, this is normal. > When system is installed completly we ran dd on the system a constant average of > 2.1MB/s is the BEST performance we could get! Check that the write cache are enabled on all your SATA disks in CTRL-M objects->physical drive. I have run the 150-4/6 at over 100MB/s in FreeBSD so there should be no problem with this setup.
