Performance - Sign Filter

[l2aze.Em]

hey guys,
i've got a performance related question.
i'm working on a config with a username filter.
i.e. i want to filter usernames that contain certain signs.
lets say the signs are "@", "-" and "+".
now i could do this by a few if-statements in loliscript:

IF "<USER>" Contains "@"
SET STATUS FAIL
ENDIF
IF "<USER>" Contains "-"
SET STATUS FAIL
ENDIF
IF "<USER>" Contains "+"
SET STATUS FAIL
ENDIF

or i could do this with a simple keycheck:

KEYCHECK 
  KEYCHAIN Failure OR 
    KEY "<USER>" Contains "@" 
    KEY "<USER>" Contains "-" 
    KEY "<USER>" Contains "+" 

now the question is: what's the best way of doing this?!
are they performance-wise the same? is one faster than the other?
is there a third way that's even better?!

The debugger has a timer that tells you exactly how much time is required to run a config. You could use that to determine which one is faster.

Also, for your particular problem, there is indeed a 3rd very fast way: using data rules. You can find rules in Configs -> Other Options -> Data and in your specific case you would set up a rule like this one

@Ruri
awesome! thanks a lot! this third way is exactly what i've been looking for.
concerning the debugger-timer though: isn't that affected by all the output the debugger got to print?!
so that's why i figured debugger timings and runner timings differ...

Yes of course but if you just put those lines (instead of a whole config) the printed stuff will basically be the same.
