So instead we are going to take a cut down version of the HammerDB TPROC-C driver script and do the same in Python and use the HammerDB infrastructure to measure performance. (We use stored procedures because, as the introductory post shows, using single SQL statements turns our database benchmark into a network test). usr/local/bin/tclsh8.6

TCL was designed as a language to be closely tied with C/C++ and at this lower level there is the compiled TCL (tclsh) or TCL/TK (wish) interpreter and supporting libraries. The include directory contains the platform specific C header files for this purpose. These bin and lib directories are not included with the source code.

Fortunately the HammerDB TPC-C/OLTP workload intentionally has a great deal of contention between threads and is therefore ideal for testing spin-locks. Copyright (C) 2003-2018 Steve Shaw.

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.
