Thomas,

Thanks for  the reply regarding my slow ftp download issue.  I tried the 3.3 
snapshot you referenced.  This did improve the download performance 
dramatically on Debian Linux/Java 6 but it actually decreased performance on 
Windows 7/Java 6 at the same time.  I tried 3.1 and performance was much better 
on both platforms.  A summary of my test results follow:

Linux 6      1.6.0_31 32 bit       3.12

Given those results I am inclined to use commons-net 3.1 for the time being.

Hi John,

this is most likely related to https://issues.apache.org/jira/browse/NET-493
Could you try with the latest 3.3-SNAPSHOT from here:
https://repository.apache.org/content/groups/snapshots/commons-net/commons-net/3.3-SNAPSHOT/

Thanks,

Thomas
