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:
Dowload of a 300MB binary file: Commons-net ver. Protocol OS Java ver. Elasped Time (min) ===================================================================== 3.2 Ftp Win 7 64 bit 1.6.0_41 64 bit 2.6 3.2 Ftp Debian Linux 6 1.6.0_31 32 bit Fails after hours 3.3 snapshot Ftp Win 7 6 4bit 1.6.0_41 64 bit 8.28 3.3 snapshot Ftp Debian Linux 6 1.6.0_31 32 bit 11.08 3.1 Ftp Win 7 64 bit 1.6.0_41 64 bit 2.48 3.1 Ftp Debian Linux 6 1.6.0_31 32 bit 4.96 3.1 Ftps Win 7 64 bit 1.6.0_41 64 bit 2.53 3.1 Ftps Debian Linux 6 1.6.0_31 32 bit 3.62 3.1 Ftps Win 7 64 bit 1.6.0_41 64 bit 2.53 3.1 Ftps Debian Linux 6 1.6.0_31 32 bit 2.45 3.1 Ftps Debian 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. John Deviney 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
