Most slow queries can now be finished within 100 ms.

By using resource control, multiple databases are now consolidated into one TiDB cluster, without worrying about noisy neighbor issue. Some workload can also take advantage of idle resource by using BURSTABLE feature.

Resource group settings can even be adjusted dynamically when necessary.
