👁 MariaDB mariadb-slap benchmark with settings of Clients: 32. Pre was the fastest.

👁 MariaDB mariadb-slap benchmark with settings of Clients: 64. Pre was the fastest.

The MariaDB performance was also appearing to take a slight performance hit from the new BIOS / microcode.

👁 WireGuard + Linux Networking Stack Stress Test benchmark with settings of . Pre was the fastest.

The biggest change in performance observed was for the WireGuard networking/VPN benchmark with around a 10% hit to the performance from the new microcode.

👁 Perl Benchmarks benchmark with settings of Test: Pod2html. Pre was the fastest.

👁 Perl Benchmarks benchmark with settings of Test: Interpreter. Pre was the fastest.

When running some scripting/interpretive single-threaded benchmarks, the run on the new CPU microcode/BIOS was beginning to indicate some regressions.

👁 PyBench benchmark with settings of Total For Average Test Times. Pre was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: go. Pre was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: chaos. Pre was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: float. Pre was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: nbody. Pre was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: pathlib. Pre was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: raytrace. Pre was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: xml_etree. Pre was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: gc_collect. Pre was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: json_loads. Pre was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: crypto_pyaes. Pre was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: async_tree_io. Pre was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: regex_compile. Pre was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: python_startup. Post was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: asyncio_tcp_ssl. Pre was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: django_template. Pre was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: asyncio_websockets. Pre was the fastest.

👁 PyPerformance benchmark with settings of Benchmark: pickle_pure_python. Pre was the fastest.

And then against all the Python scripting benchmarks run, it was a clear sweep that the new BIOS/microcode was trending lower on this Intel Core i9 14900K desktop.
