A micro-benchmark of stored routines in MySQL

Ever wondered how fast stored routines are in MySQL? I just ran a quick micro-benchmark to compare the speed of a stored function against a “roughly equivalent” subquery. The idea — and there may be shortcomings that are poisoning the results here, your comments welcome — is to see how fast the SQL procedure code […]

Interesting MySQL and PostgreSQL Benchmarks

I had found pile of MySQL and PostgreSQL benchmarks on various platforms which I have not seen before. Very interesting reading. It does not share too much information about how MySQL or PostgreSQL was configured or about queries. Furthermore MySQL and PostgreSQL has a bit different implementations (ie SubQueries avoided for MySQL) so do not […]

MySQL’s INNODB_METRICS table: How much is the overhead?

Starting with MySQL 5.6 there is an INNODB_METRICS table available in INFORMATION_SCHEMA which contains some additional information than provided in the SHOW GLOBAL STATUS output – yet might be more lightweight than PERFORMANCE_SCHEMA.

MySQL and Openstack deep dive talk at OpenStack Paris Summit (and more!)

I will present a benchmarking talk next week (Nov. 4) at the OpenStack Paris Summit with Jay Pipes from Mirantis. In order to be able to talk about benchmarking, we had to be able to set up and tear down OpenStack environments really quickly. For the benchmarks, we are using a deployment on AWS (ironically) […]
