As I understand it a I/O read is a I/O read and will take the same time whether it goes into an array or is processed line by line. The only advantages I can see to using the array approach are
1) You have to pass over the file more that once (which doesn't seem to be your case)
2) You are locking the file and want to reduce the amount of time that it is locked for, the script would take the same time, but the file would be availble to another process faster.

On another note if you are looking to squeeze every second out, your second and subsequent if statements should be elsif() statements, that way one the match is made for a given line the rest of the tests get skipped. This of course assumes that each test is exclusive.

PS the scary part to me is that I recognze the file format you are trying to parse
