Early Ubuntu Hardware/Software Survey Data

With the Ubuntu Hardware/Software Survey that was introduced in Ubuntu 18.04 and presented to users upon new installations, it's been collecting data since the Bionic Beaver launch in April but the data hasn't been made public up to this point. Viewing the survey data is currently being worked on for the Ubuntu 18.10 cycle and today a first look at these numbers have been shared.

Wine 3.10 vs. Ubuntu 18.04 vs. Windows 10 Desktop Performance

Here are some fresh benchmarks comparing the performance of a variety of cross-platform Windows/Linux desktop applications when benchmarking the native Windows 10 binaries, the Windows binaries under Wine 3.10 on Ubuntu 18.04, and then the native Linux binaries itself on Ubuntu 18.04. All tests were done on the same system and these results do a good job at showing the potential (and shortcomings) of Wine from a performance perspective.

Some Compiler Performance Benchmarks With The Zapcc Caching Compiler

Here are some quick benchmarks I ran this week of the newly open-sourced Zapcc C++ caching compiler based upon LLVM/Clang and compared to the upstream Clang performance, GCC, and Ccache with the speed on the original compilation of the benchmark code and then again on a subsequent compilation.

Intel Hyper Threading Performance With A Core i7 On Ubuntu 18.04 LTS

Following the news yesterday of OpenBSD disabling Intel Hyper Threading by default within its OS over security concerns and plans to disable Simultaneous Multi Threading for other processors/architectures too, here are some fresh Intel HT benchmarks albeit on Ubuntu Linux. The OpenBSD developer involved characterized HT/SMT as "doesn't necessarily have a positive effect on performance; it highly depends on the workload. In all likelihood it will actually slow down most workloads if you have a CPU with more than two cores." So here are some benchmarks using a current-generation Intel Core i7 8700K six-core processor with Hyper Threading.
