if speed is of the essence and only relatively few of your files contain the keywords you are looking for then I would go for a quick'n'dirty check of these keywords without bothering about the surrounding lines. Just save the name of the file in a file and have another script extract the keywords and surrounding lines from the files listed.

Also note that alterations are rather slow in a regexp and by using Regexp::Assemble you may be able to construct a regexp that runs faster.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
