The test case is to sum to 10000000.

execution time:

C++ native: 6ms
Sol3.3.1 + lua5.4.4: 253ms
LuaBridege3 + lua5.4.4: 284ms
Sol3.3.1 + luajit2.0.5: 56ms
LuaBridege3 + luajit2.0.5: 7ms

lua.script(R"(
        x = 0;
        for i = 1, 10000000 do
            x = x+i;
        end
 )");
// sol took 56 ms
// luabridge took 7ms

int x = 0;
for (auto i = 0; i < 10000000; i++)
{
  x0 += i;
}
// took 6ms

did you load the jit module with lua.open_libraries(sol::lib::jit)?
