= tcpspray -n 3000, I get ~470K/sec. This seems slow to me, but I'm not sure.

It seems VERY slow to me!  On our Novell net, we get 470K disk
transfer rate across the net.  You should be getting higher than 75%
efficiency of 1.25MBps (10Mbps).  In other words, I think you'd be
getting around 900K/s or more.

Is this just way off-base?

Just out of curiosity folks..... how does everyone's ethernet connection
rate in terms of speed? I'm running 1.1.95 (on two machines, one a p5-90,
the other 486/33) with ne2000 clones using bnc connectors. According to
tcpspray -n 3000, I get ~470K/sec. This seems slow to me, but I'm not sure.
Could some of you mail me with your stats for this for comparison purposes?

Thanx!

Well, I don't have tcpspray, but I get 1,000 Kbytes/second transfer
rate, going from disk cache on a sparc 5 to /dev/null (I'm interested
in network speeds, not disk speeds) on my 486DX2/66 with an SMC Elite 16.
That's about 8Mbps, which isn't bad at all for effective throughput on
an ethernet.

Great... just great. So somethings not kosher. Hmmm. I wonder now how to go
about looking for a cause...

N!

1. Connection speed on 10/100 MBit ethernet

Hi!

I have a big problem with the connection speed between a Linux box and a
WinNT machine. The Linux box has a 100Mbit STP ethernet connection to a
10/100 Mbit switch. The WinNt machine is connected to the switch via a 10
Mbit STP cable. Samba works good.
Problem: The Linux box sends data with 100Mbit/sec to the switch, the switch
can't transmit the data at the same speed to WinNT and sends errors back to
linux. They seem to be data overrun errors, I just can see them in
netstat -i as transmit errors (Can I get more details about them somehow?) .
I think that slows down my connection (or can it be something else?). There
are no receive errors! I get transfer rates of about 65 kbytes/sec from
Linux to NT and about 600 kbytes/sec the other way (over Samba and FTP). I
know it is far away from 1MB/sec I've heard about, but the latter is better
than nothing. Are there any settings I can change?
Could anyone help? I have no idea how to find out more details or a
solution.
Any help by e-mail or in this newsgroup appreciated!

Thanks in advance!

Stephan
