OK, checked it and found similar symptoms.  It seems to be a
continuation of the TCP_NODELAY saga with openssh.  I thought it was
fixed once and for all, but it seems they managed to screw it up
again.

Try sftp, that should behave similarly to sshfs, since they use the
same protocol.

Here's a horrible hack to work around this issue.  Cut and paste the
following script to /tmp/ssh-hack

-------------------------------------
#! /bin/sh

export DISPLAY=dummy
exec ssh -X $5 /usr/lib/sftp-server
-------------------------------------

then do

   chmod a+x /tmp/ssh-hack
   sshfs -ossh_command=/tmp/ssh-hack ...

and that should fix the upload speed issue.  I'll talk to the openssh
folks.

Thanks,
Miklos
