[Lua性能] 小试验一例

local s1 = os.clock()
local list1 = {}
for i = 1, 100000 do
    list1[#list1 + 1] = 1
end
local e1 = os.clock()
print("runtime1 = " .. (e1 - s1))

local s2 = os.clock()
local list2 = {}
local index = 1
for i = 1, 100000 do
    list2[index] = 1
    index = index + 1
end
local e2 = os.clock()
print("runtime2 = " .. (e2 - s2))

output:

runtime1 = 0.008
runtime2 = 0.003
