Interpreter performance #30

typeness · 2017-12-09T22:22:28Z

I compared it with C++ and Python. Although slow it's not that bad. Only ~3.4 times slower than Python default interpreter.

time java -jar intp-0.1.2.jar test.intp 

real	0m20.845s
user	0m21.236s
sys	0m0.260s

i = 0
while (i < 10000) {
  j = 0
  while (j < 10000) {
    j = j + 1
  }
  i = i + 1
}

time python test.py

real	0m6.061s
user	0m6.028s
sys	0m0.036s

i = 0
while (i < 10000):
    j = 0
    while (j < 10000):
        j = j + 1
    i = i + 1

clang++ test.cpp -o test -std=c++11 -O0
time ./test

real	0m0.241s
user	0m0.240s
sys	0m0.000s


int main() {
  int i = 0;
  while (i < 10000) {
    int j = 0;
    while (j < 10000) {
      j = j + 1;
    }
    i = i + 1;
  }
  return 0;
}
