Updated MTest in post #162 to include a RC5 JSCRIPT9 regex test. I'm not sure I'm using RC5 CActiveScript in the most efficient way for this test, it's my first time using it. Perhaps Olaf will chime in with a better test.

Consider the following search string:

String$(1000, "a") & "123def456ghi"

And the following regex string:

"[0-9]+"

I get the following matches/second when compiled for PCRE2, VBScript, and JScript9 via RC5 ActiveScript via

Code:
PCRE2   : 310,399 matches/s
VBSCRIPT: 161,249 matches/s
JSCRIPT9: 100,765 matches/s
