speeding up Net::FTP

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

greetings fellow monks. I have assembled a perl script utilizing Net::FTP on Windows. Aside from the documentation for Net::FTP, I was wondering if there are any tips or tricks settings that will maximize the download and upload transfer speed when I run the script. ...OR.... Is there something even better within the perl / perl module world?
Your help is greatly appreciated. Thanks in advance for your generous insite and wisdom.

You will need to provide a few more details about the nature of your application in order to get meaningful feedback. FTP is FTP -- there isn't much to set to change its behavior as a protocol. Are you making sure your system has optimal bandwidth from your network? Are your files compressed before your transfer? If your files are coming from/going to different systems on different networks, you could run transfers concurrently, using lots of different mechanisms	[reply]

Net::FTP::Throttle can help you. It can "throttle" the maximum bandwidth to optimize transfer speed.	[reply]

You might tune your TCP/IP stack if you haven't done so. Google for tuning ftp to find guidance if this is unfamiliar. Update: I found http://www.csm.ornl.gov/~dunigan/netperf/bulk.html particularly interesting, though it may not be applicable to your situation. Update: And don't forget your disk I/O, system bus, etc. The network may not be your bottleneck.	[reply]
