Hi everyone,
Does any one have any idea regarding the said title? I'm just
trying out the latest rtl8139too driver code from realtek on my
LEAF-based machines. I'm using my own 2.4.x kernel and I noticed
that the stock RTL driver codes are not performing satisfactorily
with my on-board RTL8100C cards.
The latest driver code seems to work pretty well. I just just
figured it's best if I can really compare my results with actual
FTF P2P (at least) standards.
Any links are also very much welcome.
BTW, sorry for this OT post. You guys are the only credible
individuals I know regarding Linux networking ;o).
In my everyday experience (on a multi-host LAN, not p2p), 10 Mbps cards
actually top out at about 5 Mbps. I recall that Don Backer used to have a
Web page explaining the reason for this limitation, but I lost the
reference long ago. That limit applies to any high volume transfer -- ftp,
scp, smb -- and, in my case, both ne and 3c509 NICs (maybe others too).
I typically see a maximum of about 70 Mbps with 100 Mbps cards (usually
tulips from different sources, but others too, including rtl8139, 3c95x,
dmfe, and eepro100) ... scp, ftp, or smb, usually in settings where the
transfer was the only substantial traffic on a quiet LAN. But I've seen
reports from others over the years that they can run at nearly 100 Mbps (on
networks that have only 2 NICs present), but I don't recall what service
was involved in those tests.
