Need Help??

in thread Perl always reads in 4K chunks and writes in 1K chunks... Loads of IO!

This:

open DF, "test.txt" || die "Can't read 'test.txt': $!\n"

Does not do what you think it does.

The || ties itself to "test.txt", which is always true, and not to the return of the open.

This:
open(DF, "test.txt") || die "Can't read 'test.txt': $!\n"

or:

open DF, "test.txt" or die "Can't read 'test.txt': $!\n"

(or binds less tight than ||)

Would accomplish what you want.
