in thread Question about benchmarking

Thanks for that information about benchmarking, that is exactly what I needed. Btw, what I meant by "I don't trust it because it is too simple" is that it looked like too simple of a solution to what looked to be a complex problem, but really wasn't.

For those who still want to see the code, here it is (I've removed all of the stuff that doesn't have to do with the hierarchy part, to cut down on confusion):

#!/usr/bin/perl # *********************** # Name: # Author: Joe Ryan # Date Finished: August 10th, 2001 # Where Used: # Description: An extension to that lets the # user browse through the amherst website, showing the hits # per directory and per file. Note that the script # doesn't directly run off the weblog, but rather a text # file that is created after processing the weblog. open(DATA, 'pagehits.txt'); @mlines = <DATA>; close(DATA); $cutat = 2; # recursive function that prints the hierarchy sub print_hierarchy { my ($newlevelref, $newhitsref, $x, $stophere, $plvars, $temp, $tem +p1, $resume) = @_; my (@newlevel) = @$newlevelref; my (@newhits) = @$newhitsref;

} $plvars = "&pathlevel0=$path[$#path]"; $endpath = $path[$#path]; if ($path[$#path] eq $pathlevel0) { print_hierarchy(\@newlevel0, \@newhits0, 1, $stophere1, $plvar +s, $temp, $temp1, $resume); } $p_count = ($endpath =~ /\.//);

} print "</table></body></html>";

I'm sure I can scope a lot of these variables a little better, and I'm sure that their are some more efficient ways to do some of the things I was doing (via a built-in function, etc.). If anyone sees anything at all to help sprouse it up, by all means tell me!
