Actual throughput of a 100Mbps small home network???

[Guest]

I have two Xp MCE2005 computers (one is P4 2.4 and the other is a P4 2.8 and
both NICs are set to 100 full-duplex) networked with a Dlink DI604 Broadband
10/100 Router. Doing some quick test copying large media files (5-8GB) from
one computer to the other it seems that actual throughput averages about
64Mbits/s (8 MByte/s)

Is this normal? I know there is network overhead.. but I didn't think this
much.

Testing this setup they are both in the same room, with good quality patch
cords.

Another question is, what is normal real world throughput if it I upgraded
to a Gigabit switch and cards?

Have you check www.D-link.com for firmware upgrade to your router. I know that
the DI-624 is rated for 108MB/s with the firmware installed.

The DI-604 may be set for approximately 10MB/s, so your 8MB/sec may be the norm.

Those answers do not match the question. That router may do 108 Mb/s on its
wireless leg, but not 108 MB/s. Likewise, the wired leg may be set to
10 Mb/s,
not 10 MB/s.

8 MB/s seems a bit slow. Using two XP PCs to copy files using Explorer's
drag'n'drop, I get ~9.9 MB/s pushing a large file, and ~9.5 MB/s pulling it.

My 100 Mb/s switch is part of a Linksys WRT54G instead of your DI-604, but
I don't know if that matters. And the two PCs I used are a 3.0 GHz P4 at
one end, and a 2.0 GHz AMD at the other end; your PCs should be fast enough
to do as well as I did.

Make sure you are using a large single file instead of a bunch of smaller
files, since that minimizes file overhead. And, make sure your CPUs are
running near-standalone and that your HDs are not the bottleneck.

Also do your testing while logged into both PCs with the same credentials
(username, password). With some earlier testing I did in a mixed (XP/W9x)
environment, this made a huge difference; I don't know if it does in a
pure (all XP) network.

Finally, measure your transfer rate with a stopwatch. Some apps mis-report
transfer rate.

Yes, I am using large MCE dvr-ms files 2-8 GBs in size (one at a time) and
using NetStatLive to measure throughput. Doesn't seem to matter which way
the file goes, it doesn't change more than .1 MB/s

I guess this whole exercise started when I saw that the price of a Gigabit
switch and nic would be about $50 (one comp already has gigabit Nic) , and I
wanted to make sure I didn't have a cabling/setup problem that would limit
the benefit of going Gigabit. I know it's not going to go up by a factor of
10. But if it went up 2x or 3x that would be nice considering the low price.
