MySQL Beats Sybase and PostgreSQL in Neal Nelson Power Efficiency Test

Share Article

In recent tests of both throughput and power efficiency, the MySQL Database Management System delivered superior results when compared to several other popular DBMS packages, including Sybase (NYSE: SY) and PostgreSQL. For example, MySQL delivered 101 to 299 percent more throughput and 107 to 328 percent better power efficiency when compared to Sybase. These tests were run on an AMD (NYSE: AMD) Opteron based server by the independent computer performance consulting firm Neal Nelson & Associates.

    The Nelson Database Power Efficiency Benchmark measures both throughput and power efficiency for transaction processing workloads at a variety of user load levels. It runs identical workloads on the same server platform with different DBMS software packages to determine differences in throughput and power consumption that are caused by the DBMS software. To demonstrate that significant differences exist, and that these differences can be measured by the new benchmark, Neal Nelson has released preliminary test results for Sybase, MySQL, PostgreSQL and DISAM96.

The Database Power Efficiency Benchmark is a client server benchmark where World Wide Web transactions are processed against a server configured with Novell's SUSE Linux Enterprise Server operating system, the Apache2 web server and various different database management software packages. The benchmark subjects a server to multiple user load levels, reports the throughput and power consumed at each load level and provides meaningful comparisons of both throughput and power efficiency.

Nelson's firm has a long history of computer consulting for some of the world's largest computer users including the U.S. Army, U.S. Navy, the Internal Revenue Service, McDonalds, WalMart and Federal Express. Nelson operates a benchmarking laboratory that is available to commercial and government users for independent computer performance tests. The tests described above were not financed or sponsored by any company or group.
