Adam Slagell commented on BIT-1215:
-----------------------------------

We are going to make it configurable and default to like a 1000KB line. Otherwise, you add a check to see if you need to reallocate memory for every line processed, which seems inefficient for edge cases. Letting the user override the default is a good compromise though.

> The current implementation of bro-cut is too slow when processing large log files (takes more than a minute to process a single log file a few hundred MB in size).  Justin Azoff rewrote bro-cut in C and found that it runs an order of magnitude faster.  Another benefit of a C version of bro-cut is that we will no longer depend on gawk for anything (and some of Bro's supported platforms do not include gawk by default).
