perf: Optimize SimpleVirtDriver See merge request opendc/opendc-simulator!52
2020-04-06perf: Optimize SimpleVirtDriverFabian Mastenbroek
This change optimizes the SimpleVirtDriver by removing unnecessary cancellations (which take a lot of time due to exception construction). Moreover, we now try to keep intermediate state sorted so that we do not have to re-sort every scheduling cycle (which was rather heavy as profiling showed).
