I also experience 100% CPU load during upload. However, I'm using plain
ftp, this is my config file:

open ftp://myuser:mypassw...@ftp.livedrive.com
mirror --continue --reverse --verbose=3 --delete
/Backup/.obnam_repository_encfs /Backup/.obnam_repository_encfs
close
exit

I don't understand the proposed workaround and I before applying it, I'd
like to know what side effects should I expect if I tune my system that
way. Can you please help me with this?

I saw one bug report similar to this, but it is marked as solved:
https://github.com/lavv17/lftp/issues/39
Should I comment on that with my problem or open a new one?

I'm using lftp 4.6.1.

Thanks in advance for your help.
