Subject [jira] [Created] (NET-519) Apache Commons Net 3.3 has a performance issue
Date Fri, 22 Nov 2013 00:59:35 GMT
Bambi Edgar Mota created NET-519:

             Summary: Apache Commons Net 3.3 has a performance issue
                 Key: NET-519
             Project: Commons Net
          Issue Type: Bug
          Components: FTP
    Affects Versions: 3.3, 3.2
         Environment: Windows 7
            Reporter: Bambi Edgar Mota
             Fix For: 3.4

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.
