You should ignore the time it takes the first time, because that is used to read pieces of program and data into memory, which varies a lot, in addition to the time it takes to run the program. The second time, it is already in memory, so the time is largely the time to run the program. That's why it is a lot faster and also more consistent, which makes it a more reliable way to do comparisons relative to other solutions..

replace(1) MySQL database replace(1)
NAME
replace - A utility program that is used by msql2mysql, but that has more general applicability as well. replace changes strings in place
in files or on the standard input. Uses a finite state machine to match longer strings first. Can be used to swap strings.
USAGE
replace [-?svIV] from to from to ... -- [files]
or
replace [-?svIV] from to from to ... < fromfile > tofile
SYNOPSIS
replace [-?|-I] [-s] [-v]
DESCRIPTION
replace
-?|-I info
-s silent
-v verbose
EXTRA INFO
Special characters in from string:
^ Match start of line.
$ Match end of line.
Match space-character, start of line or end of line. For a end the next replace starts locking at the end space-character. A
alone in a string matches only a space-character.
EXAMPLE
this command swaps a and b in the given files:
shell> replace a b b a -- file1 file2 ...
