This is great that you continue your work in this direction! The concept of scan that you propose looks interesting.
I have few questions:
1. Charts are measured in percents of pgbench TPS, right?
2. For example, is 97% actually 3% degrade?
3. The results are obtained on actual "sort of TPC-B" script?

Best regards, Andrey Borodin.
