Lua benchmark: closures vs. coroutines

bench.lua

local times = 100000

local start = os.clock()
for i=1,times do
	local closure = function()
		print("test")
	end
end
print(os.clock() - start)

local closure = function()
	print("test")
end
local start = os.clock()
for i=1,times do
	local co = coroutine.create(closure)
end
print(os.clock() - start)
