Benchmarks
Benchmarking extracting all files from ISOs across various systems against wit:
System 1
(Linux 5.9, 16 GB, AMD Ryzen 9 4900HS)
| Command | Mean [ms] | Min [ms] | Max [ms] | Relative |
|---|---|---|---|---|
wit x melee.iso ./extracted |
727.1 ± 11.1 | 716.1 | 769.0 | 2.20 ± 0.05 |
gcm extract melee.iso ./extracted |
331.1 ± 6.2 | 321.9 | 345.9 | 1.00 |
System 2
(Windows 10, Ryzen 7 3700X, on SSD)
| Command | Mean [s] | Min [s] | Max [s] | Relative |
|---|---|---|---|---|
wit x GALE01.iso ./extracted |
8.551 ± 2.532 | 6.942 | 15.378 | 2.09 ± 0.83 |
gcm extract GALE01.iso ./extracted |
4.092 ± 1.082 | 3.056 | 5.732 | 1.00 |
(Windows 10, Ryzen 7 3700X, on HDD, in single thread mode)
| Command | Mean [s] | Min [s] | Max [s] | Relative |
|---|---|---|---|---|
wit x GALE01.iso ./extracted |
10.452 ± 1.812 | 8.898 | 13.982 | 1.00 |
gcm extract --single-thread GALE01.iso ./extracted |
11.810 ± 1.838 | 9.372 | 14.135 | 1.13 ± 0.26 |
System 3
(Windows 10, on HDD, multithreaded mode)
| Command | Mean [s] | Min [s] | Max [s] | Relative |
|---|---|---|---|---|
wit x melee.iso ./extracted |
109.495 ± 6.301 | 105.039 | 113.950 | 1.20 ± 0.25 |
gcm extract melee.iso ./extracted |
91.584 ± 18.295 | 78.647 | 104.520 | 1.00 |
Note: Multithreaded mode will harm performance if the ISO is on some form of physical media, such a hard drive.
