Same file on the same machine - error "501 Invalid number of arguments" in the 4.2.1 listing and the time taken to complete the listing and transfer.

Transferred 1 file totaling 3.61 MB in 0.42 seconds (10.52 MB/s) -> version 3.6

Transferred 1 File (3.61 MB) in 5 seconds (683.0 KB/s) -> version 4.2.1

I have had the revert back to version 3.6 as tranferring lots of small files is taking forever with 4.2.1


thanks
