But since retrieving data from disk is slow, databases tend to work with a caching mechanism to keep as much hot data, the bits and pieces that are most often accessed, in memory. In MySQL, considering the standard storage engine, InnoDB , the data cache is called Buffer Pool. In PostgreSQL, it is called shared buffers.
A monitoring tool like Percona Monitoring and Management (PMM) is a popular choice among opensource options for effectively monitoring MySQL performance. This includes metrics such as query execution time, the number of queries executed per second, and the utilization of query cache and adaptive hash index.

The same data, in the form of pages inside the Wiredtiger cache, are also marked dirty. At every checkpoint interval (Default 60 seconds), MongoDB flushes the modified pages that are marked as dirty in the cache to their respective data files (both collection-*.wt Download Percona Distribution for MongoDB Today! wt and index-*.wt).
The project consisted of upgrading the shop software to our own open-source system and redoing the shop’s front end from scratch. And while you can usually cache the full page of an article, the same is not true of many shop pages and elements. This keeps us from having to download 10 or more additional font files.
