First: I've occasionally mentioned all kinds of performance issues
over the last years. I even started threads on how to improve things
on a completely new level.

I can provide many performance annoyances that affect me on a daily
basis.

So I am glad to be able to improve the situation for anybody. I have
had slow agenda performance for many years and I had to live with
it.

Here is a current profiling report from my daily agenda:
