Background
Cross-platform (any computer with Java) DiglloydTools IntegrityChecker runs SHA1 hashes on files to maintain data integrity checks. These days with so many Apple bugs, any professional should be using it to validate their data integrity, especially with macOS Finder silent data-loss risks and outright bugs when copying files.
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. Performance on an 8-core system can be up to 3 GB/sec if the I/O speed suffices
Results: IntegrityChecker verify
The 2019 MacBook Pro takes only 15% longer than the 2019 iMac 5K, a percentage difference remarkably consistently across many different workloads.
