Yes, it is more expensive. On my machine (W2K 750MHz PIII) this code:
for i=1,100000 do
local f = getglobal("Test_Version")
f()
end
Executed in 0.12 seconds, while this code:
for i=1,100000 do
dostring("return Test_Version()")
end
Executed in 1.262 seconds.
So about a factor of 10 slower.
However, I have to say that 12.62 microseconds to execute the
"dostring" version is pretty darn fast, plenty fast enough for many
situations.
