 Hi all,

 I've just try the 4.0b5 (r7501) build today ... It doesn't seems that the
 "fix" is working here. Is there something to configure somewhere ?

 sftp (command line) is around 5MB/s when cyberduck is around 80KB/s on the
 same file in SFTP mode and 300KB/s for scp mode.

 Worst : If I try the 3.7 (r7380) then the SFTP mode give me ~150KB/s and
 scp one around 300KB/s ... looks like a regression to me, or ?

 Any way to get any debug from cyberduck ? I saw in the sources some log
 stuff, but didn't get anything in the preference panel to see where the
 log goes ...

 Thanks for taking care of this one. Some of my users are trying to push
 ~40GB at 150KB/s ... ouch.
