Without microvacuum: 1st run | 2nd run
Time: 259.996 ms | 246.831 ms
Time: 169.820 ms | 169.501 ms
Time: 176.045 ms | 166.845 ms
Time: 169.230 ms | 167.637 ms
With microvacuum: 1st run | 2nd run
Time: 625.883 ms | 425.231 ms
Time: 10.891 ms | 10.603 ms
Time: 10.002 ms | 10.971 ms
Time: 11.613 ms | 11.643 ms
