Mono Code Size Measurements Results from my own tests in December 2012
The following are based on accessing a local integer variable (ordered by size) Instruction ByteCode size (x); 2 (~x); 3 x+x 4 x=~x; 5 x=-x; 5 ++x; 6 x=x+x 6 x=-~x 6 equivalent to ++x x=~-x 6 equivalent to --x x = !x; 7 if (~x); 7 if (x != -1) x++; 8 x=0; 8 x=1; 8 x+=1; 10 x-=x; 10 x=x*2; 10 x*=2; 10 if(!~x) 10 if (x == -1) x *= -1; 11 x<<1; 12 if(x<0); 13 if(x==-1); 14 x=x<<1; 14
List storage Requirements in Mono These figures differ from those given in http://wiki.secondlife.com/wiki/LSL_Script_Memory Maybe Mono has been tightened up a bit.
Integer 16 bytes each
Float 16 bytes each
String 18 each plus 2 bytes per character
Key (valid keys)
(stored as keys) 102 bytes (!!) per key
Key (valid keys)
(stored as strings) 90 bytes per key
(key) "" 30 bytes
Vector 24 bytes each (correction, oops^^)
Rotation 28 bytes each
