I built my first Perl application that parses XML and creates a website of over 1000 pages from that XML. The build process is really fast. As a last step, I wanted to take all the generated files and copy them to a new folder and then zip them up for another process to pick up and FTP to another location.

I had trouble getting a recursive copy of everything, and inquired here at perlmonks, where someone suggested, since I was using ActiveState, to use the ActiveState::Handy::cp_tree module.

I installed it and ran it local. It copied all 1000 files to another directory (in the same root folder of the project, same hard drive, etc) in maybe a minute. Great so far!

I took the entire Perl application and put it on a network box so other people can build the site. I mapped a drive (windows of course) to the folder on the network, and executed the program. The entire build process was as fast, if not a little faster than on my laptop.

But...when it came time to execute the last section of the code, where I use cp_tree to copy the newly generated files to an "out" folder, the process completely bogs down.

I can watch the out folder slowly fill up with files, about 1 per second or something like that. Now, the simple copy command is taking about 10-12 minutes from start to finish, whereas on my laptop, it only take about 2 minutes.

Any clue what could be going on? Does Perl behave differently if you invoke it from a mapped drive or network resource? Why would one section of code fly on one machine and be so slow, impossibly slow, on another?

Thanks for any help. I'm brand new to Perl and this is my first project with it.

Thanks...

Doug
