with the TPROC-C workload on a system with 2 sockets of Intel Xeon 8280L that means we have 28 cores per socket, with 56 physical CPUs and 112 logical CPUs with Hyper-Threading. Plotting these data points enables us to understand the scalability of the database software being tested on that system. and MySQL 8.0.25 and MySQL 8.0.25

Fortunately the HammerDB TPC-C/OLTP workload intentionally has a great deal of contention between threads and is therefore ideal for testing spin-locks.

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.

When taking this approach you would not focus on the test result but instead monitor the databases ability to cope with the variation in demand and transaction response times. This is because Virtual User 1 is the monitor Virtual User but this Virtual User does not run in the replica meaning it ends immediately. Step Workloads.

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.
