Thomas Neidhart commented on NET-519:
-------------------------------------

This is most likely related to this issue.
There reports on the user ml that there is still a slowdown in 3.3 compared to the 3.1 version.

>    Affects Versions: 3.2, 3.3

> We use Apache Commons Net FTP 3.1. That version had a bug for transferring files with
size 0 that was resolved in Apache Commons 3.2.
> Apache Commons 3.2 and 3.3 however both have a performance problem for files that do
not have a size of 0.
> For example a 30MB file using 3.1 takes approximately 40 seconds on our system from point
A to point B. 
> Using Apache 3.3, the same file takes 2 minutes and 5 seconds. 
> Using Apache 3.2, the same file took over 4 minutes. 
> This is not acceptable. 
> If there are any workarounds, we would like to know. If not this is a major bug.
