To demonstrate the performance overhead and requirements, here are some numbers from a standalone APM Server deployed on AWS EC2, under full load receiving APM events containing only traces, assuming no backpressure from Elasticsearch, and 10% sample rate in tail sampling policy. They are for reference only, and may vary depending on factors like sampling rate, average event size, and average number of events per distributed trace.
