We hope you will consider supporting us today. We need your support to continue to exist, because good entries are more and more work time. Every reader contribution, however big or small, is so valuable. Support "Chess Engines Diary" even a small amount– and it only takes a minute. Thank you.

Raising a pull request early as 24 Thread tests are very expensive and 
this is clearly a positive gain at high thread counts and high time 
controls. The change is a small parameter tweak with no additional 
logic. 

No functional change for single thread mode.
