- monix 10y agoPeople that end up in a position to care about performance are using profilers and bechmarks. This is actually the first rule: don't guess, measure. Of course it helps when the platform has the proper tools for it. I end up using JMH and YourKit Profiler weekly, because a memory or CPU leak can crash our process and we have pretty strict reliability requirements with a single server processing about 5000 events per second - not extremely demanding, but when it crashes, we can lose money, with the redundancy infrastructure being pretty new.
