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.
I am planning to do a general in-depth analysis of single-threaded performance to look for things that can be improved. I plan to look at different relevant use-cases, not restricted to replication. I just blogged about a large improvement in in-memory read-only sysbench. (This i the reason I asked you a couple months ago about interesting loads to analyse for single-threaded performance regressions). My experience is that whatever I take the time to look into, I always find significant opportunities for improvement that are relative easy to achieve. - Kristian.
