fastest transfer method I have seen.

Post by Dongxiao Y » Sun, 19 Jun 1994 23:40:58



 Hello,

  I was using slip connection from my newly installed linux .
  I found using ftp on linux, the through put is constantly 1.6Kbytes/sec
  when I do binray transfer of precompressed files(*.Z). While
  I have one telnet connection and run ftp on another connection the
  through put is still 1.5Kbytes/sec. The cpu usage of th ftp program
  is very small.

  I used kermit. and zmodem before the best was 1050 byes/sec.
  I also used  slip ftp  program for DOS, the throughput was only  
  500bytes/sec.

  I am using a 14.4K modem.

You should get much better with ZMODEM (or even Kermit-94).
For an example, here are the stats for recent uploads of files >100k
to psu through their terminal server system accessed at 14.4kb.
The fifth field is the characters per second throughput.

For me, I get better throughput on ftp/SLIP than on Zmodem.  I think
TCP/IP are actually quite efficient.
