About
Cross-platform (any computer with Java), IntegrityChecker Java runs SHA512 hashes on files to maintain data integrity checks. All professionals should be using it to validate their data. Especially when random “land mine” bugs in new macOS releases pop up, such as macOS Finder silent data-loss risks and outright bugs when copying files.
Or bad memory or bit rot (rare but real), etc.
The verify command of diglloydTools IntegrityChecker utilizes all CPU cores as efficiently as any application ever can, using sophisticated I/O algorithms to feed data to the CPU as fast as the OS can go. Performance will thus be gated by I/O speed unless all CPU cores are fed data fast enough to be fully utilized.

Results
The results here are all limited by SSD speed, which is slower on the Intel Macs. As a practical matter, there is no difference on the Apple Silicon machines but they all trounce the Intel Macs.
The Apple M1/M2/M3 Mac internal SSDs all run in the 6.7 GB/sec range.
The 2019 Mac Pro can actually hash at 12+ GB/sec on a faster SSD, but its results as shown here are on its Apple internal SSD, which maxes-out at ~3.4GB/sec.
The 2022 Mac Pro M2 Ultra can actually hash at an astounding 29 GB/sec, but only a PCIe SSD like the OWC Accelsior 8M2 could deliver something approaching that speed eg ~22GB/sec. Pity that Apple did not see fit to “pro” the Mac Pro vs its siblings by doubling its internal SSD speed.
