I am looking for some published paper regarding database performance
tunning performance strategies. This is for academic purpose so it
needs not to be any commerical database specific. It will be even
better if the paper has some kind of methods to quantify/measure
performance. Has anyone come across with any interesting paper about
this?
Thanks,
ewong

Ahmmm. It was my aim to match the performance of C and I achieved that
aim very early on. See, for example "The Design and Evolution of C++".

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

For most users, this new feature is actually very convenient. If you want to control the update process,...
