The flip side of speeding up delivery, however, is that each software release comes with the risk of impacting your goals of availability, performance, or any business KPIs. Typical Dynatrace use cases cover SLOs for service availability, web application performance, mobile application availability, and synthetic availability.

Resource groups permit assigning threads running within MySQL to particular groups so that threads execute according to the resources available to this group. MySQL determines, at startup, how many virtual CPUs are available. Then we need to see IF implementing the tuning will work or not. I am talking about resource groups.

We focus on a definition that draws from the following two principles: (1) the value of temporal locality, by classifying as cold a memory page that has not been accessed beyond a threshold of T seconds; (2) a proxy for the application effect of far memory, by measuring the rate of accesses to cold memory pages, called promotion rate.

QUIC is needed because TCP, which has been around since the early days of the Internet, was not really built with maximum efficiency in mind. ISPs and intermediate networks might block it because metrics such as average delays and packet loss percentages are no longer easily available, making it more difficult to detect and diagnose problems.
