I think you should outline your use case/problem in more detail. This 
should be a good practice when asking for support on the Mailing List.

Example:

1) I have a text file where each line contains a two integers separated 
by a space (" ") char - such as (possibly paste a part of the file on 
pastebin or similar too).
213214 12313
123223 13213

2) My file is [always/at least/circa/ ...] 2,539,592 lines long

3) My algorithm should find all subsequent lines matching the first line 
in the file and return [all line numbers for matches / the total count 
of matched lines / ...]

3) I want the algorithm to be [as fast as possible / run in under 1 
second / run in under 1ms / ... ]

4) I [want to / do not need to] use Pd Vanilla

5) My patch should run on [All platforms / Windows / OSX / Linux / ...]

6) My patch should run [on potentially any machine / on a Raspberry Pi / 
on a 1990s 386 machine / on my digital toaster where I have compiled a 
custom version of Pd / ... ]

:)
