How to Assess MySQL Performance

HammerDB

Instead, focus on understanding what the workloads exercise to help us determine how to best use them to aid our performance assessment. This all sounded very similar to HammerDB TPROC-C workload (we will look at HammerDB TPROC-H (OLAP) another time), so it is easy for any reader to think both workloads are about the same. and 8.0.32

GotW #97 Solution: Assertions (Difficulty: 4/10)

Sutter's Mill

(Note that “no side effects on normal execution” is always automatically true for violation handlers even when an assertion system such as proposed in [4] allows arbitrary custom violation handlers to be installed, because those are executed only if we discover that we’re in a corrupted state and so are already outside of normal execution.

Let's Write Some x86-64

Nick Desaulniers

So a whole Babel of computer languages has been created for programmers: FORTRAN, BASIC, COBOL, LISP, Pascal, C, PROLOG, FORTH. This blog is meant for those who don’t know x86-64 assembly, but maybe know a little C, and are curious about code generation. But you never can tell exactly what the compiler is doing. Dan Gohman.

A persistent problem: managing pointers in NVM

The Morning Paper

Byte-addressable non-volatile memory,) NVM will fundamentally change the way hardware interacts, the way operating systems are designed, and the way applications operate on data. The Twizzler KVS (key-value store) is just 250 lines of C code, and uses one persistent object for the index structure, and a second one for the data.

The top 5 reasons to run your own database benchmarks

HammerDB

For example the following chart (with the actual data removed for the reasons described further in this post) shows the HammerDB TPC-C workload run against the same database on different processing architectures (grouped by colour) and speed with the most recent at the top.
