I found the answer. The solution is to get a hardware raid. You're using the raid solution on your motherboard, and because of that, your write performance is terrible. I found this out after about 4 days of tring to find a solution.

This command was first published by Maxxuss (where are you?) when he wrote the kext for VMware network card. Keep up with your great work Quixos!

sudo sysctl -w net.inet.tcp.delayed_ack=0

This Command worked on my real IMac(G3 Tray loading) years ago. My Real IMac had the same exact problem with slow smb file transfer(but not high cpu load). On my systems anyway it is slow upload speed to the Mac.

From Windows - Copying or moveing files from XP to Mac=SLOW
however copying a file from the mac to Windows was fine

From Mac - Copying or moveing eather direction is fine.

It seems that OS X is limiting the thansfer speed when uploading to the IMac. If I used Linux or even OS9 speeds both directions were fine it was only OS X sad to see things have not changed over the years.
