Archie Cobbs writes: Last May I encountered a relatively obscure performance bug present in both MySQL 5.5.x and MariaDB 5.5.x (not surprising since they share the same codebase). This turned out to be a great opportunity to see whether Oracle or the MariaDB project is more responsive to bug reports. On May 31 Oracle got their bug report; within 24 hours they had confirmed the bug — pretty impressive. But since then, it's been radio silence for 3 months and counting. On July 25, MariaDB got their own copy. Within a week, a MariaDB developer had analyzed the bug and committed a patch. The resulting fix will be included in the next release, MariaDB 5.5.33.
