When I start X, xfdesktop is a mostly idle process as I'd expect.
When I transfer a file to my system with ncftp, xfdesktop starts to take
80%-100% cpu.
And it keeps on doing that, for minutes afterwards.
This is a i7-4790K system with 32 GiB memory and a SSD, so that is an insane
amount of cpu time.
I can reproduce this - it always happens with file transfers and never happens
without.
This is the result of strace -c (started during file transfer and ran for a few
minutes afterwards,
ended while xfdesktop was still at 100% cpu):
