+Прогнав по значениям в диапазоне от 250 до 10000 RPS получилось найти точку разладки
+в 2300 RPS, стабильно работает при 2000 RPS, связи с профилированием в виртуалке, 
+RPS не очень большие. 
+
+Прогонял до 10000 потому что выявил что в Linux-ubuntu при длительном нахождении Idea ultimate
+в пассивном режиме(не открывал среду разработки) любое количество RPS в среднем давало Latency 4s, 
+пока не понял с чем связано
