Since a long time I observed that my ftp transfer rates are not what they
should be. I carried out yesterday a one-to-one comparison between Windows
and Linux and the results speak by themselves. The test was done as
follows:
Download and upload between a Pentium II PC (200 MHz, 128 MB RAM)
with either Linux (kernel 2.0.36 or 2.2.13) or Win98 operating system and
a SGI Indy workstation, across an ISDN telephone line (max. speed 8 KB/s).
and a pair of ZyXEL Prestige 100 routers, one at each end.
A 3 MB file was transmitted to and fro. In the Linux case I used
either plain ftp or the more comprehensive program nftp (www.ayukov.com).
In the Windows case I used the very excellent Wincmd program
(www.ghisler.com).
The results (rates averaged over 3 MB transferred data):
Linux OS : download 6.175 kB/s, upload 7.190 kB/s
Win98 OS : download 7.746 kB/s, upload 6.721 kB/s
For Linux, the above results are the best I got. Using Midnight
Commander the results are slightly worse (e.g. 5.7 kB/s download) with
kernel 2.0.36 and *catastrophical* with kernel 2.2.13 (practically
unusable for download).
For Windows, better results are obtained with Windows on both
sides, using Laplink 7.5, the transfer rates are consistently 7.5-7.6
kB/s in both directions, so that I tend to think that the inferior upload
result above is related to the Indy workstation.
