well, to solve this problem i made some tests

with this code

alias teste_speed {
var %i = 0, %time = $ticks
while (%i < 100000) { inc %i }
echo total time $calc($ticks - %time)

i tested the average times is .txt .mrc and .ini
the times that the alias took to run were the same iven for the ini file that has extra chars in it!!

you can try for your self

no need to thank me wink
