…which reminds me to use Callgrind more often.

Good work, thanks

A slow scrolling of a listview reminds me of the “all effects” list in the system settings. There are no stars in this list. But maybe there is a similar issue there?

Nitpick: it’s more like 625 times faster, since the .04% you measured is from much less total time as well.

Great to hear! Is this fix going to make it into 4.5.1 or 4.5.2 or not until later?

Thanks for the blog post and your excellent work.

I’m wondering how we can leverage general users’ observations on such things into bug reports. I know that I’ve noticed slowdowns sometimes, but I’ve never done anything about it – and I don’t have the technical expertise to identify the issues like you did. So maybe a clear explanation on how to report bugs about slowdowns (including pasting in a log from callgrind or other tools, for example) would be really useful. Just an idea..
