For now, I have only tested this C/C++ code on a dedicated Intel i7-3770 3.4 GHz 4-Core 'home' computer as the VPS is used for a more stable python version (accumulating huge delay) especially at market opening. In the end, it will probably stay on a AMD Ryzen 9 3900X 3.8 GHz 12-Core dedicated...

Do not have the figure right now, but as far as I remember it was higher than I expected it in the profiler. I gained some time by not using a JSON parser with its nodes and all, but parsing C-string the old-school way ;-) That parsing is done already in independent processing threads. But, I...
