Predicting application performance is a difficult art, but an important one when choosing the target deployment environment. Among the different components of modern software solutions, the database is one of the most critical. Benchmarking the target Two of the more popular database benchmarks for MySQL are HammerDB and sysbench.

For optimum performance, a PostgreSQL database depends on the operating system parameters being defined correctly. Poorly configured OS kernel parameters can cause degradation in database server performance. Therefore, it is imperative that these parameters are configured according to the database server and its workload.
