Re: Network problem...



Hello all
ok.. but what can be done to get better throughput with the Accton/ Realtek interface ?
or can I forget to get any better performance ?

Hi Michael
Well the old "default" interface "tlp0" delivered a better
throughput.. and that's just plain old 10Mb Ethernet, whereas this
one is 100Mb

I doubt it. 1.1MB/s is pretty much the physical maximum you can
squeeze through a 10MBit/s ethernet interface, your results are both
higher although you're right, a fast ethernet interface should go
faster.

Right.  The tlp should perform better than the rtk; they are both
100mbit/sec interfaces but the tlp is significantly less burdensome
on the host cpu, which is almost certainly the bottleneck here.

The tlp in this machine is a 21041 which does only 10MBit/s

This test is getting and putting files from the disk drive.  I am
not surprised that a very old PowerBook cannot send data it has to
read from its internal hard disk faster than 27Mbit/sec.

A better test would be to use ttcp.

Or something bigger - 10MB hardly gives consistent results.

have fun
