A 100MBit Network - as you have (I am talking about Mega Bytes). On a
100MBit Network, you should be able to handle 12.5MBytes of data
transfers. Removing all the TCP/IP overhead etc. you should be able to
handle approx 11MBytes (88MBit) traffic. In full-duplex of course this
would make that amount of traffic in each direction.
Now - coming back to your 800KBytes/s transfers, you have a 6.4MBit
connection, which is even bad for a 10MBit Network (From my experience,
you can do better than that - 1MBytes/s is a good value I have already
reached in past.
The Machines I have are a Celeron 900MHz with 1 Gig Ram, and a Athlon
1.3GHz with also 1Gig Ram. Once you copied an ISO-Image onto a Ramdrive on
the source machine, and on the target machine too - you can be able to
measure pretty well the Network performance while ftpying the file over.
I also don't do use the ftp-software to define the connection speed, but
the time used to transfer the file using "time ncfgpget URL"
That way, I know how well my systems perform ;)
The Funny thing is, that in Full-Duplex Operation, you should get while
copying a 350MByte file at the same time in both directions, approx
75MBits Transfer rates :) Well - there seem to be some collisions. Most
probably the ACK-messages...
PS: And all for the sake of having a decent UT2003 Network *lol*
Cheers
