warm up
To run a system under a typical workload for some time after startup, so that the buffer pool and other memory regions are filled as they would be under normal conditions.
This process happens naturally over time when a MariaDB server is restarted or subjected to a new workload. Starting in MariaDB 5.6, you can speed up the warmup process by setting the configuration variables innodb-buffer_pool_dump_at_shutdown=ON and innodb_buffer_pool_load_at_startup=ON, to bring the contents of the buffer pool back into memory after a restart. Typically, you run a workload for some time to warm up the buffer pool before running performance tests, to ensure consistent results across multiple runs; otherwise, performance might be artificially low during the first run.
