Which settings are you using for a 1-CPU droplet @DigitalOcean?

Basic settings, on extra large instance (sieve size 1M, sieve percentage 10, round sieve size 30): 4.5k PPS, 550 5-chains/h

Current best tweaked settings (so far), on extra large instance (sieve size 250k, sieve percentage 3, round sieve size 45): 5.7k PPS, 840 5-chains/h

Looking for best 5-chains/h

Lower sieve sizes are better, on extra large instance (sieve percentage 10, round sieve size 30):
- 100k: 6.6k PPS, 660 5-chains/h
- 250k: 5.6k PPS, 650 5-chains/h
- 500k: 4.9k PPS, 650 5-chains/h
- 900k: 4.6k PPS, 600 5-chains/h
- 1.1M: 4.4k PPS, 540 5-chains/h

Lower sieve percentages are better, on extra large instance (sieve size 1M, round sieve size 30):
- 1: 7.1k PPS, 640 5-chains/h
- 2: 6.5k PPS, 600 5-chains/h
- 3: 5.6k PPS, 800 5-chains/h
- 4: 5.2k PPS, 670 5-chains/h
- 5: 5.1k PPS, 610 5-chains/h
- 15: 3.7k PPS, 510 5-chains/h

Higher round sieve sizes are better, on extra large instance (sieve size 1M, sieve percentage 10):
- 20: 4.1k PPS, 440 5-chains/h
- 25: 4.5k PPS, 550 5-chains/h
- 35: 4.4k PPS, 660 5-chains/h
- 40: 4.2k PPS, 730 5-chains/h
- 42: 4.1k PPS, 740 5-chains/h
- 45: 4.0k PPS, 735 5-chains/h
- 50: 3.8k PPS, 500 5-chains/h
