Performance

• sim2010 classic mode 2-120 days 2e7pkt 960 core Virgo runtime decreased from 915.7 core hrs (v2024.02.17) to 776.8 core hours (12% faster). Compared to classic (5741.5 core hours) this is 7.39x faster.
• W7 (Shingles et al. 2022) NLTE nebular 960 core 2e9pkt 150-410d Virgo decreased from 4888.0 core hrs (v2024.02.17) to 4358.7 core hrs (12% speedup).
