Hi guys,
I've made a small list of functions, showing how much time they lag, and how fast is there response:

// VAR.clear() :: 0.001213s
// echo() :: 0.001369s
// VAR.clearvars() :: 0.001739s
// VAR.leave() :: 0.001903s
// findobject() :: 0.002094s
// findplayer() :: 0.002352s
// VAR.join() :: 0.002423s
// findlevel() :: 0.005151s
// VAR.setlevel2() :: 0.007743s
// VAR.getfunctions() :: 0.485558s
If you know Gs2, you should use most of these almost everytime (except the last). But you should know how much lag/time does it take to let them load.
As you can see, it's quite slow, whereas real programming languages usually takes a-lot less time.
