I believe that you are correct in that there is an alternative answer. Without posting a long script, here is the premise:
while logfile {
if (certain conditions are met)
push @portArray, $_ ## pushes certain elements of the $_ into array, protocol and port number
The array will look like the following:
80 TCP
443 TCP
137 UDP
80 TCP
80 TCP
25 TCP
.
.
.
This becomes a very long list. From here I would sort and then sequentially step through the array. If the current line does not look like the last line the print the last line and the number of times it was counted. The output looks as follows:
TCP 80 - 25
TCP 443 - 32
TCP 25 - 837
UDP 137 - 23
That logic was based on the sort function. Any help would be great, I have a couple of ideas to make it faster that I am going to try.

Is there a faster way to sort? Thank you in advance > for your help. Perhaps the answer lies in not sorting the data at all :-? If you explain the problem that you're solving with a sort, perhaps we can suggest an alternative.
