[SLE] inferior performance of Linux ftp
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.

For some of us close those would be great. mine are between .9 to 3.5 depending on the phone lines. -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/

It's good to hear that on average Linux is better...(and free): Linux 6.6825 kB/s W* 7.2335 kB/s Cheers, Alvaro -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/

I'm curious now. . .I have seen exactly the opposite. I have used plain old ftp also with no problems and it's faster and more reliable than my windows machine. I will have to do a side-by-side to prove it now though. I have an adsl connection and I hit a sustained rate of 800 kbps on a 100 M transfer I did the other day. Though I was not using the linux ftp client. I was connecting to my linux box as a host using ws_ftp on my winNT box at work and the host was running wu_ftp for the server at home. Still I thought that was an impressive rate. Maybe I can test the client some tonight to see if I get the same results you do there. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Darren R.

I've seen Linux stomp Windows into the ground as a server. Transferring a 25MB file from Linux+Samba was 50% faster than from Windows. Identical hardware for servers and clients.
