Yow ! 1135 KB/s remote host TCP bandwidth over 10Mb/s ethernet. Beat that!
Well, let's try beeing serious. This is the performance I measure between
two Linux machines on our network. The theorical maximum TCP performance
(assuming zero collides and delays) is 1155.92 KB/s on an ethernet 10 wire
! (Stevens, TCP/IP illustrated). I'm astonished by this results, within 2%
of the theorical maximum.
This measurements are done with tcpspray. Each one is done on 140.000.000
bytes, in just two minutes. The results range from 1135 to 1140 KB/s. The
boxes are equipped with some cheap 3c509 cards. The network is fully
switched, and the two hosts are separated by five switches. The
inter-switches lines are full-duplex ethernet 100.
Of course, the performance of other OS'es isn't comparable : about 1000
KB/s connecting to WinLoose 95, and about 875 KB/s connecting to an
UltraSparc 1 box running Solaris.
