New user here (before even having installed the software). I was unable to find any hardware recommendations. What are the HW requirements for a VPS? Would somebody be willing to share his current cloud setup?

As asked, your question is pretty abstract because we have no idea what tasks are planned. View some charts or run optimizations all week long? That's gonna make difference.

Still, even more important is to avoid a cheapo VPS that doesn't lend itself to determine its unique hardware fingerprint. WL8's protection system won't even let start it up on such:

Thanks for your quick response Eugene.
I had already read both of the linked articles. I should have hinted that I am looking for a backtesting/optimization server and not so much for a trading host:
1) Does WL8 need a GPU if I will only use a single display?
2) The biggest Windows VPS at the suggested hoster IONOS (VPS Windows XXL) only has 24GB RAM (and BTW no GPU!). Seems to be very little. Will WL8 profit from much more RAM eg. 256GB when doing optimizations and/or backtesting? Should I go for as much RAM as possible?>
3) Does WL8 backtestiung and optimization work better with many (>8) "weak" cores (eg. Intel Xeon) or does it prefer fewer but "faster" cores (eg. Intel i7/i9)
I'm just looking for a decent configuration for evaluation.

WL doesn't address the GPU for its calculations. Obviously, WPF does to do its GUI display graphics, but you already knew that.

The absolute minimum requirement is 16GB RAM. I think you would be somewhat faster with 32GB RAM, but that really depends on the size of your problem and how tight you write your code (i.e. Principle of Locality).

Definitely fewer but faster cores in all cases. But some things to remember:
a) The amount of on-chip cache is the most critical thing. A fast processor won't do you any good unless the entire problem can fit into its on-chip cache. There's a speed penalty of a factor of 10 for cache misses. Keep the footprint of your problem as small as possible to maximize cache hits.
b) Only the optimization operation is multithreaded, so adding more cores will not speed things up unless you're optimizing. You'll run out of cache memory before you run out of cores, so you may want to limit the number of active cores to 3 or 4 during optimization. You'll need to experiment with that.
Happy engineering to you.

I have the same, it's not enough to make genetic evolver work properly.
My first test with KVM on Ubuntu 22.04 failed miserably due to your hardware token issue. Why don't you just verify proper license use online?
Finally I went for an dedicated server at Hetzner with an AMD Ryzen 9 3900 CPU (12 cores, 64MB L3 cache) and 128GB RAM for EUR 62/month which seems to be more than enough for backtesting.
Overall I'm fairly happy with your product and will buy a license. Thanks for your help.

Congratulations on your success and we hope your Wealth-Lab experience will be smooth and profitable.
