Are there other goals for single-thread performance regressions? There are many that have nothing to do with replication code although almost every single-threaded replication hurts replication. On Mon, Jan 20, 2014 at 2:54 AM, Axel Schwenke <axel@askmonty.org> wrote:
Hi,
for those of you who didn't attend the Barcelona meeting last week, here are the plans for next steps in benchmarking:
1. top priority is automatic running of DBT3 for each new release of MariaDB-10.0 and MySQL-5.6. Probably also for MariaDB-5.5. I'll send out another mail to pinpoint DBT3 conditions (i.e. which table statistics to use etc.)
2. multithreaded replication slave is now in a condition that it can and should be benchmarked
3. the problem pointed out by Yoshinori in
http://yoshinorimatsunobu.blogspot.de/2013/12/single-thread-performance-regr... must be checked for MariaDB. Monty announced that he will commit a patch this week that should help with that problem.
4. for the NUMA scalability problem, Kristian will try to find the definitive reason with profiling tools. Besides that ad-hoc testing of new patches from Svoj continues as before.
5. Galera benchmarking will be done by the Galera team for now.
