#374 closed Bug report

Upload slow to Mac OS X

Reported by: anonymous Owned by:
Priority: normal Component: Other
Keywords: Cc: Tim Kosse
Component version: Operating system type:
Operating system version:


Uploading a file to MAC OS X (v10.2.x) using its built-in
FTP server (lukemftp) is slow (~100KB/s) for version 2.1.

I also tried v2.1.4 and it uploads at 4.1MB/s, so
something has been broken. No speed limits were in

I guess this is a similar problem to the one someone has
with uploading to an Xbox.

I have seen this problem with many comercial and
freeware FTP apps such as BPFtp, CuteFTP. A few work
properly - LeechFTP, WS-FTP.

Strange thing is that on my system 2.1.8 is faster than any
other version.

I need some more information about your system:

  • Windows version
  • CPU speed
  • amount of RAM
  • Are you using any firewall?
    • if yes, have you tried to upload with the firewall disabled?
  • Any background virus scanners? Try to disable them
  • Type of connection to the 'slow' server (LAN, Modem,

Cable...) including max. connection speed

  • If possible, your TCP parameters like MTU, RWIN...
