Hi, I am manipulating a large file ~ 1gb and my program seems to be very inefficient. At the moment my plan of attack is to read it by paragraph, analyze the paragraph and write to a new file. this is convenient as the paragraphs within the file need to be analyzed separately. I hope this is not too vague a question but is there a more efficient way of doing this? apart from the way Im doing it; 
$/ = "";
open(F, "<$infile")   or die "Could not open $infile for a reading!\n"
+;
while ( <F>) {
  my $line = process_paragraph($_);
  print OUT2, "$line\n";
}

hopefully somebody could point me in the right direction Cheers
