For me personally, its things like ray tracing and fractals.
However, just for the record, I kind of find that argument less valid these days. If you have a GUI application, and that's all
you are doing and its just basically responding to events with pretty trivial actions, then basically you can get the same
performance pretty much until the CPU starts hitting 100% utililization during peaks. That leaves a lot of room for a language
(and its libraries) to eat up CPU cycles without making a noticeable difference in performance in that kind of 'one user driven
app' situation.
But these days a lot more tends to be going on. I tend to have network stuff going on in the background, compiles going on in
the background, image generation, etc... In such a situation, the argument above falls down because that 'slop area' is no
longer free. In that kind of situation, even 10% more CPU utilization driving the GUI (or other non-problem domain grunt work
that does not directly contribute to the job at hand) takes valuable time from other things going on. The more CPU constrained
the workstation, the more that this is true. In a workstation that's doing industrial control, heavy graphics, video, etc...
using the most efficient language possible can make a difference. All of those extra cycles, though never really grotesque in
any one operation, begin to add up.
