Actually, this is a lot of small files (48KB mean size).
Speed is roughly 2 Mbps which is low for a 100 Mbps.

Or by zipping up all the file before FTP'ing them, assuming this is for a
remote backup application that could unzip them at the other end.

You never reach 100 Mbps which is faster than many disks. Once you have
large data size, you overflow the cache mem
Hello Arno,
Also avoid/minimize LIST command's use as much as possiblebetween
file's upload, this can take time especially if directory has many
files inside.

Hi,
I've written a FTP-uploader without taking much care of speed issues.
It uploads 17000 files with total size of 830 MB in 56 mins in my
100 MBit/s LAN (logging each FTP-command).
What do you think, is that:
a) Poor
b) OK
c) Fast
I currently don't have any idea.
