why this code runs faster ???

[startup]

Care to share how you solved it?

ok
let step back

when i concat with " _ " the code runs very fast

when i concat with "_" the code runs so slow
[/FONT][/SIZE]

i was totally wrong here
the slow was in displaying the message

i put the message for debugging purpose
so i detect finally that is no difference between concat with " _ " or concat with "_"
both are fast
no need for dialog message that consume time
simply i remove the dialog message line :yes

thanks shrek for trying help


any one know why ??

concat function too slow when i put 1 char
then become so fast when adding another char to it ??

Try it with pure Lua:

my_table [COLOR="#FF0000"]=[/COLOR] [COLOR="#FF0000"]{}[/COLOR]

[COLOR="#0000FF"]for[/COLOR] i [COLOR="#FF0000"]=[/COLOR] [COLOR="#000000"]1[/COLOR][COLOR="#FF0000"],[/COLOR][COLOR="#000000"]300[/COLOR] [COLOR="#0000FF"]do[/COLOR]
 [COLOR="#0000FF"]table.insert[/COLOR](my_table[COLOR="#FF0000"],[/COLOR][COLOR="#0000FF"]math.random[/COLOR]([COLOR="#000000"]111111111[/COLOR][COLOR="#FF0000"],[/COLOR][COLOR="#000000"]999999999[/COLOR]))
[COLOR="#0000FF"]end[/COLOR]

Dialog[COLOR="#FF0000"].[/COLOR]Message([COLOR="#800080"]"Notice"[/COLOR][COLOR="#FF0000"],[/COLOR][COLOR="#0000FF"]table.concat[/COLOR](my_table[COLOR="#FF0000"],[/COLOR][COLOR="#800080"]"_"[/COLOR]))

[startup]

first code

my_table = {}
for i = 1,300 do
num = Math.Random(111111111, 999999999);
Table.Insert(my_table, i, num);
end
Concated = Table.Concat(my_table, "_", 1, TABLE_ALL);
Dialog.Message("Notice", Concated, MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1); 

run very slow

second code

my_table = {}
for i = 1,300 do
num = Math.Random(111111111, 999999999);
Table.Insert(my_table, i, num);
end
Concated = Table.Concat(my_table, " _ ", 1, TABLE_ALL);
Dialog.Message("Notice", Concated, MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1); 

runs very fast

the deference is in line 5
in the table.concat function

when i concat with " _ " the code runs very fast

when i concat with "_" the code runs so slow

i need to Concat with "_"
can i know why slow ??
is there a solution ??
