I was mostly coding in C, tuning FORTRAN, and when I needed to do a lot of data analysis of benchmark results used the S-PLUS statistics language, that is the predecessor to R. The SE toolkit was fast, had no memory leaks (monitoring scripts could run for years) and let me implement lots of cool performance monitoring ideas.

In particular on Intel Scalable Processors (Skylake architecture) the PAUSE instruction is much longer than previous architectures and therefore calling UT_RELAX_CPU can consume a lot more time resulting in reduced performance.
