That reminds me of when I first discovered the difference in speed between BASIC (on the Commodore VIC20) vs "Machine Language", back in the early 80's. I was blown away. :)

had a routine written in 'c' to search for stuff in the ftp log on our linux server, which is currently going on 17Mb.

it was taking a 'long time' so i wrote it in assembly (intel). intel has a special instruction to look for chars. that helped.

old time was 1.415 sec. new time is 0.020 sec. 70 times faster. now i get the result as soon as i hit the Enter.
