The tar.gz and deb binary packages for MariaDB-5.5.23 (checked: tar.gz for Linux-x86-64, deb for Lenny/amd64) don't use native AIO. This can be seen in the error log: the message about InnoDB using native AIO is missing. And also "ldd mysqld" does not list libaio.so.
Since AIO has rather big performance impact, binary packages should be built with AIO support, at least those packages that come with explicit dependency support.
