Re: Website engines
Hi Guenther,
Apologies, I must have been drinking when I replied to this before. Yes the Google V8 Javascript engine that node.js is built around - and which Lozza runs in - improves all the time. The latest V8 version is v8.7 but it'll take a while to get into node I guess. The V8 engine in my fairly recent node is v8.4 (node version 14.15.3).
Use this command to find out:-
node -p process.versions.v8
So yes, well worth an upgrade
Thanks for what you do...

I can confirm that replacing my old version of Node (5.0.0.0) against the one I am using now with WukongJS (11.0.0.0)
gives a speedup of 401 kn/s vs. 352 kn/s ~ +14% => this was with lozza 1.18 from the startpos after around 150s
Meanwhile I also checked that the last available version for WIN7 would be 13.6.0.0, may be I try that one too later.

Awesome
I sat watching Lozza do a soak test yesterday in Cutechess GUI getting to depth of between 8 and 20+ at 50ms/move; the google V8 Javascript engine is very impressive.
Thanks again.
