Hi, I am using one Power G5 and Intel pro,both with MAC OS X 10.4.Each machine is having two 1Gbps network cards inbuilt.But when i transfer data between these machines using ftp(scp) , i am getting only 50MB/s only. My harddisk transfer rate is 150MB/s (Also 7200rpm ).Each system is having 1GB RAM. It would be really helpful if any one tell me ,what could be the reason for lower transfer rate.

Hi Nithin,

are you using RAID arrays of some sort? A normal hard disk does not have a sustained transfer rate of 150MB/s (those 150MB/s are the theoretical limit of the physical interface SATA, as soon as the hard drive's buffer is filled it is the transfer speed to the platters that matters, which is typically a lot lower than the SATA speed) 50 MB/s sustained is pretty good for a hard drive. So, the reason is your process is limited by the speed of the hard disks involved.

HTH,
Horst
