He was using a benchmark which he said, "We run our system in productions, so we know the behavior and we have done the benchmark part and they pretty matched with regard to whether it is GC or CPU utilization or network I/O in most of the situations. The problem is, he said, "I cannot take anything from my production environment and have the confidence of repeatability running on the systems." Then, what I go run for traditional benchmark, etc., that we find. Very few of them are very large, we go up to 100 gig heap. We run them usually in two or three gig heap. They said, "I have around 3,000 to 4,000 applications, some of them are very small footprint." These are microservices that talk to each other and some of them are very small, like two gig. That lead me to ask the very first question to that person: "What are you running?" This is a pretty large company. Where my production ranges with regard to 30% to 40% operational, then I see this 60% to 70% variability from run to run and that start to gave me some idea, "What is going on here? Because we don't see such things." What Test Is Running? One is full capacity metric, when system is fully utilized, only in case everything else fail and only fuse system are carrying the load, then performance is very repeatable. I got this email from Dev one and a half month ago or so, "We are evaluating this Intel latest platform and I'm doing this runs and I'm getting a variability of almost 40%, 50%, 60% from run to run," and I'm, "No, I have not seen such things." You can see the two metrics he was talking about. My expertise comes more from the benchmarking area, performance and responsiveness. I've seen there are other talks about the monitoring part, so this track also does not cover the monitoring. Second one was the monitoring and observability, that have not been great in 7 or 8 and there have been significant improvement. I think there is a talk later in which I'm not that involved in licensing there are other experts. There were definitely three issues, one was related to what are the licensing terms.
