Hi Guys,

I'm wondering what's the maximum sustained transfer rate
that one can experience when using a 100Mbps link?


Is there any way that I can determine what's the bottleneck?
FYI, I'm using iftop.

Transferring files between 2 PCs, (laptop and Desktop)
I see like up to 20MB/s.


Could this # be limited due to my slow HD? 4200rpm which
hdparm -t (or is it -T) gives ~26MB/s

1mbps = 1024/8 bits = 1 MB/s (I know there's a conversion
but I'm forgetful)


Cheers, Mun Heng, Ow








Without compression and overhead 100Mb/s transtales to about 12.5MB/s..

Of course that is the theoretical maximum..

If you add overhead and contention you will probbaly see an actual transfer of between 60Mb/s and 90Mb/s..

I am not sure how you have managed to see a throughput of 20MB/s on a 100Mb/s link..

Later..
