Gigabit transfer rates

drew and not u · September 29th, 2008

Just picked up a gigabit switch today to replace the previous 10/100 unit I used. There are 3 gigabit capable computers connected to it directly, and all 3 PCs show 1Gb/s connection status. With my previous switch I only ever saw ~10 transfers over the network. After switching to the gigabit switch I've gotten as high as ~280Mb(35MB)/s, but transferring a batch of 100MB .rar's it only transferred at ~96Mb(12MB)/s.

These transfers are only between gigabit machines directly connected to the swtich. Does this seem normal to anyone else or does it sound like I have a bottleneck?

It sounds to me like it's probably being limited by the hard drives, if anything. They'll only be able to write the data being transfered to them so fast, so the speeds you're getting sound reasonable to me.

I pondered that, but the drive being written to is a raid 0 array with 960Mb(120Mb)/s average transfer rate. The drives being read from are all modern SATA2 drives with high transfer rates.

What are you getting those numbers with?

I haven't used any actual utilities, these are the numbers Vista is giving me. Any recommendations as far as good network monitoring utilities?
