As part of the curiosity-driven benchmarks and areas of technical interest now that we've gotten some of our initial Intel Xeon Platinum 8380 "Ice Lake" benchmarks out of the way has been looking into the performance of Linux's P-State CPU frequency scaling driver on the 3rd Gen Xeon Scalable server. Benchmarked for the latesting testing was the power/efficiency out-of-the-box with P-State powersave as used by default with many Linux distributions against the P-State "performance" mode as well as putting P-State into passive mode to be able to via intel_cpufreq to try the Schedutil governor that relies on the kernel's scheduler utilization data for making frequency scaling decisions. Here is a number of power/performance governor benchmarks with the dual Xeon Platinum 8380 server in these varying kernel configurations.

Compiling source code produces a binary. During compilation, you can provide flags to the compiler to enable or disable certain properties on the binary. Some of these properties are relevant to security.

Checksec is a nifty little tool (and shell script) that, among other functions, identifies the security properties that were built into a binary when it was compiled. A compiler might enable some of these properties by default, and you might have to provide specific flags to enable others.
