Стоит ли выставлять количество uWSGI воркеров больше чем количество ядер процессора?
Документация uWSGI советует подбирать это значение практическим путём.There is no magic rule for setting the number of processes or threads to use. It is very much application and system dependent. Simple math like processes = 2 * cpucores will not be enough. You need to experiment with various setups and be prepared to constantly monitor your apps. uwsgitop could be a great tool to find the best values.
