My apologies if this comes across as a newbie question. I'm not a Perl developer, but am trying to use it within an automation process, and I've hit a snag.

The following command runs quickly (a few seconds) on my Linux system (Ubuntu 9.10 x64, Perl 5.10), but is extremely slow on a Windows system (Windows 2003 x86, Strawberry Perl 5.12.1.0).

perl -pe 's/\x00\x42\x00\x11/\x00\x42\x00\xf0/sgx' inputfile > outputfile

The pattern find/replace is intended to fix EBCDIC carriage control characters in a file that is between 500MB to 2GB in size. I'm not sure if this is even the most efficient way to do this, but it would seem to do the trick... if only it would run quickly on the Windows system it needs to run on.

Any thoughts?
