I have the latest version of BestSync and am using it to make backups of all our websites via ftp.
I have changed the limit of downloads and set this very low - but when I run the task it slows our server down. When I check the CPU using putty, BestSync is using up a lot of CPU - sometimes up to 90% - despite setting the download limit very low.
See a screenshot: http://rainbowcreative.co.nz/pics/bestsync.jpg
(The CPU is definitely being used by Best Sync, because when I stop the task the "proftpd" disappears.)
It seems to me that the speed control doesn't work... but maybe I am missing something.
Cheers and thanks,
