Dear curl-users,

i have download the program curl version
7.15.0

it runs on my pc without errors
it is wonderfull, but

upload works very slow

for example:

i want to upload a zip-file
from my pc with windows-xp-sp1
to a netware6-server
via ftp

i used the commandline

curl -T *.ZIP -u .t.ftp.skgr:passwort
ftp://172.16.3.30/

the zip-file has 100 mb

curl needs 15 minute for transfer

if i use the programm TOTAL-Commander
for ftp-upload it needs 15 seconds
if i use the ms-windows-commandline-tool
ftp for ftp-upload it needs 10 seconds

if i try to download the same file with

curl -o 20051019.zip -u
.t.ftp.skgr:passwort
ftp://172.16.3.30/20051019.zip

curl needs only 10 seconds = normal
speed

it seems the curl-program use for the
uplaod a special very slow
ftp-sub-protokoll
and for download the normal
ftp-sub-protokoll

Are there such things?

Have you any idea how i can increase the
upload-speed for my needs?
Have you any suggestions?

best regards

J.Ufer
