PlentyChess

[Jouni]

All your compiles have lost to 7.0.22. Why? Because your compile is 10% slower than official. Benches here (bmi):

your compile:
Total time (ms) : 2526
Nodes searched : 2194974
Nodes/second : 868952

official:
Total time (ms) : 2311
Nodes searched : 2194974
Nodes/second : 949794

So almost 10% difference.

And with official compile I got

Code: Select all

Reckless in danger, because PlentyChess has better scaling!?

indeed, they are slower because they are non-PGO builds (good enough for testing functionality of dev versions). i can look at making PGO builds next time.
