Slow txfer rate on LAN..why?

[jtsnow]

I have a PC, P3 600 XP SP2, on my home LAN that when it does a backup to a
network harddrive on the LAN, it only outputs data at about 10megbits/s or
about 10% of the LAN utilization and 100% CPU utilization. This is with no
other activity on the LAN. And this is doing drive image backups using
Norton Ghost 9.0. Alo

2 other PCs P4 3Ghz XP SP2, when doing the same backup operate at about
30megbits/s or about 30% of LAN capacity and less then 50% CPU utilization.

I have even swapped out the LAN card and set it for 100 duplex and still not
change.

Is there something I can do to improve the LAN transfer rate from the 1 PC?

Is it just that it take so much processing power to send ethernet data that
its slower CPU cant put out data like the other 2 faster P4s?.

If so, It surprizes me that it utilizes so much CPU cycles.

thanks for any insight

More likely its the compression thats taking the cpu horsepower.

What are you specifying for the compression ? Try the alternatives.
