Unfortunately, the performance in benchmarks is almost the same as for 4KB pages. Kubectl helps to check the amount of huge pages available. kubectl describe nodes NODENAME … hugepages-1Gi 0 (0%) 0 (0%) hugepages-2Mi 1Gi (25%) 1Gi (25%) … The tool reports only 2MB pages availability in the above output.

In short, each cluster is, in reality, a single database with high availability and other functionalities built in. MySQL router, after the 2048 connection, could not serve anything more. HAProxy performs better with a low number of connections, while ProxySQL performs better when a high number of connections is in place.

bpftrace is a new open source tracer for Linux for analyzing production performance problems and troubleshooting software. Linux already has many performance tools, but these are often counter-based and have limited visibility. This example instrumented one of many thousands of available events. bashreadline.bt biolatency.bt
