I noticed the latest blog post from Kristian after posting my question.
Haven't read all of it yet, but your work looks very good. Your blog posts
are also a great way to get more visibility for MariaDB (on Facebook and
elsewhere).

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.
