With Intel VTune. That's the software I know to use for $DAYJOB
(mainly HPC related stuff). I think there are also several free
software options available to produce flame-graphs based on profiles
recorded by perf.

I've been putting off building GnuCash myself for now, but I think
will have to do that at some point in the near future, so I'll retry
it once I get around to doing that.

Ah, yes. If I remeber correctly from the Gtk2 era, there was some
advice for disabling list sorting temporarily when inserting a large
number of items.
Although, I would have to check which gtk call in `gnc_item_list_new`
is the culprit here.
