Hi!
Playing with Mozilla's SpiderMonkey (FireFox 2.0) I've found that string operations
in js are extremely faster then in Lua. For example this js code snippet
var str="";
var cmpStr="vary long number..."
for(i=0; i <= 30000; i++)
{
str=str+i;
if(str==cmpStr)
{
}
}
is ~20 times faster then Lua code:
local str=""
local cmpStr="vary long number..."
for i=0,30000 do
str=str..i
if str==cmpStr then
end
end
Here we have number2string conversion, strings concatenation and
strings comparison...
~150 ms in FF2.0
~3000 ms in Lua 5.1.2
~6000 ms in IE6
Is it possible to improve string operations performance in Lua?
