Event Series Intelligence: Esper & NEsper
Esper exceeds over 500 000 event/s on a dual CPU 2GHz Intel based hardware, with engine latency below 3 microseconds average (below 10us with more than 99% predictability) on a VWAP benchmark with 1000 statements registered in the system - this tops at 70 Mbit/s at 85% CPU usage. Esper also demonstrates linear scalability from 100 000 to 500 000 event/s on this hardware, with consistent results accross different statements.
We have put a small benchmark kit together to enable you to measure and tune Esper performance in your environment, and for the purpose of comparing Esper performance to the performance of other CEP/ESP solutions.
The benchmark kit is described in detail in the documentation in the chapter on performance.
We are collecting platform-specific data obtained by the benchmark kit on our Esper Performance Wiki page.
