Apple 2018 Mac mini: Java Performance for diglloydTools IntegrityChecker a Big Bump Up vs 2017 iMac 5K
MPG tested the 2018 Mac mini 15-inch 3.2 GHz 64GB 1TB UHD630. Add 10-gigabit ethernet if it makes sense in your environment, and save money by getting 64GB OWC memory and upgrading an 8GB-memory Mac mini.
This test is extremely interesting: the java version of IntegrityChecker is as fast or faster than the native version. That’s because Apple has degraded the performance of various file system APIs (starting in macOS 10.12), along with introducing highly variable erratic performance for some types of disk I/O—Apple Core Rot at its finest.
The six CPU cores of the 2018 Mac mini deliver a major boost to Java-based performance for this task—the 2018 Mac mini runs at 29% faster data rate, over 2 GB/sec versus 1.6 GB/sec for the 2017 iMac 5K.
