I hope you don't take any of my comments personal. Because they are not! It is just that I am tired and bored of these every so often repeated MySQL optimized "benchmarks". I see a clear difference between a database server process crash and a disabled service caused by misbehaving sysadmin scripts and/or bad service because of contra-optimized client behaviour. This is exactly the same style of reporting crashes or bad performace, the MySQL folks have practiced for years.I remember creating and dropping tables a couple thousand times, then VACUUM with a user that doesn't havepermissions to vacuum system catalogs, and report bad performance because the system cache got successfully screwedup ... there was even a comment in the script saying "this makes Postgres slow" ... haha. Other reported *crashes* have been core dumps of the test-scripts, because Postgres dealt with datums bigger than the perl-clientwas able to swallow ... well, the test driver just reported a crash, not exactly where and why, does that really matter? MySQL shows success and Postgres does not, that's what counts. The lowest level still accepted Transaction Processing Council Benchmark, TPC-C, can be implemented with a SUTusing MySQL. Do it using LAMP, if you want to learn what a database crash is ;-) There is a good reason why TPC has abandoned the TPC-1, TPC-A and TPC-B benchmarks. They are "too simple" to be of any meaning for benchmarking purposes these days. Yet all the stuff this huge crowd of MySQL-Lemmings is constantly babbling about is even more simple than that! They all have their reasons, the TPC members (basicallyall serious RDBMS vendors) on one side as well as the MySQL folks on the other. As a matter of fact, the MySQL folks are alone with their point of view that "beeing fastest on a single-table-select" is the most important criteria for a relational database management system. And as anothermatter of fact, Lemmings get what Lemmings deserve, MySQL!
