Sorry, I made a mistake in last post. I forgot add -O2 in lua origin version.
Now test again in my windows 10 / mingw64.
CPU i5-2500k @ 3.60 GHz
origin version modified version
test 1 3.276s 1.278s
test 2 3.376s 1.413s
---- test 1 ---
function f(a)
end
local t = os.clock()
for i=1, 10000000 do
f { x=1, y=2 }
end
print(os.clock() -t)
-------------
Origin version of lua 5.3.2 : 4.977s
Modified version of lua 5.3.2: 1.278s
---- test 2 ---
function f(a)
a.x = 3
end
local t = os.clock()
for i=1, 10000000 do
f { x=1, y=2 }
end
print(os.clock() -t)
