Minefield download and browse history performance scaling

Good day/night!

I'm using Minefield for quite some time now, and I've a history for the
last month or so. Both the download and the visited pages history open
with a huge delay.

My question is that are there any average numbers for this? For a
history with ~1000 entries what times should one get?

And reordering the history panel also takes a lot of time. I'm talking
about ~10 seconds, and that's not healthy IMHO. And it completely
freezes the application.

And for the download panel, it's much better, but still not just "pops
up". And in m.d.a.firefox the Clear All button debate was because it's
fast, and don't depends on the number of files, but clearly that's not
the case. I've just deleted my DL history, and click-n-pop, it's done in
an instant.

I hope my mail is in the right group :)
