C呼叫lua指令碼的效率測試

c呼叫lua指令碼的效率測試

以下**以c語言為基準，測試了c呼叫lua迴圈和迴圈呼叫lua的效率。結論是不要頻繁地穿越c/lua邊界.

#include

extern "c"

/* lua直譯器指標 */

const char lua_script =

"function loop_add(a, b)            "

"   local sum = 0                   "

"   for i = 1, 10000000 do          "

"       sum = sum + a + b           "

"   end                             "

"   return sum                      "

"end                                "

"                                   "

"function add(a, b)                 "

"   return a + b                    "

"end                                "

;// lua 指令碼裡面的函式由c呼叫

int use_lua_add(lua_state *l, const char *func_name, int x, int y)

int main()

sum = 0;

tstart = clock();

for (i = 0; i < 10000000; i++)

tstop = clock();

printf("c++: %dms./nthe sum is %u./n",

(tstop - tstart) * 1000 / clocks_per_sec, sum);

sum = 0;

tstart = clock();

sum = use_lua_add(l, "loop_add", 1, 1);

tstop = clock();

printf("lua loop_add: %dms./nthe sum is %u./n",

(tstop - tstart) * 1000 / clocks_per_sec, sum);

sum = 0;

tstart = clock();

for (i = 0; i < 10000000; i++)

tstop = clock();

printf("loop lua add: %dms./nthe sum is %u./n",

(tstop - tstart) * 1000 / clocks_per_sec, sum);

lua_close(l);

return 0;}

執行結果：

c++: 31ms.

the sum is 20000000.

lua loop_add: 437ms.

the sum is 20000000.

loop lua add: 2360ms.

the sum is 20000000.
