I checked a map here with about 30k elements and inverting the selection took (in a slow debug build) less than 1 second. What kind of map are we talking about here? That said, I ran it through the profiler a few times, and I see that there are a few possible optimisation points, someting in the 10-20% scale. But I won't touch it unless there is a real problem at hand, so I'm curious about the map you're working on. Can I have this map to run a few tests? |
