Ubuntu 19.04 vs. 19.10 Performance On High-End AMD/Intel Desktop CPUs
For some I/O scenarios at least, the EXT4 read performance has improved with Ubuntu 19.10. Of course, there is also the non-default ZFS experimental option now also readily available to Ubuntu 19.10 users as another option.
The NAS Parallel Benchmarks are among the scientific workloads seeing superior performance on Ubuntu 19.10 thanks to the GCC 9 default compiler stack. In this very parallelized case, the Core i9 7980XE went from being slower than the Threadripper 2990WX on Ubuntu 19.04 to now being faster. Likewise, the Core i9 9900K gained more ground on the Ryzen 9 3900X.
Some of the NPB tests saw smaller gains on Ubuntu 19.10.
On several of the tests we found the Threadripper 2990WX benefiting particularly well on Ubuntu 19.10.
The TSCP chess benchmark was one of the few workloads regressing on Ubuntu 19.10.
