My system has an AMD Ryzen 9 5900X 12-Core Processor and 32GB RAM, however even with my computing preferences set to 100% CPU and 90% RAM, it only runs 5 tasks simultaneously, using about 12% of the available CPU resources.

I suspect this is a RAM limitation because I notice from Oracle VirtualBox that the "rosetta python projects 1.03" task VMs are configured with 6GB of base memory, and I presume it's no coincidence that 5 x 6 GB fits neatly into 32GB. But in reality the VirtualBox processes running those VMs are only using ~50MB each, so it seems to me the virtual machine image configured for these tasks is grossly overallocated memory-wise, thereby preventing rosetta from reaching the full potential of computing resources available.

It has been commented on from when Python tasks were first released here.
Since nothing has been done since ten, the odds of something happening in the future are as good as non existent. So systems will need at least 7.5GB+ of available RAM per Task they want to run, regardless of how little they actually use when running.

Thanks... do the people running the project even monitor this forum, or are we shouting in a vacuum here?

So infrequently as to be pretty much not at all.

If you increase the amount of memory allocated within Boinc to 90% or higher you can get up to 10 or even 11 tasks running at once if you want to push things to the limit.
I found stability issues if I tried too many at once, but 9 or 10 are much more manageable in my experience.
Experiment a little and see what you're comfortable with

I was going to reply saying I've already done that, but I had only checked the 'When computer is not in use, use at most' value, assuming that it would use this one when I had BOINC set to 'Run always'. When I increased 'When computer is in use, use at most' to match it, then I get 11 tasks like you. It's using about 35% of CPU capacity and only about 600MB of RAM... let's see how stable it is. I wouldn't really expect stability issues at those levels...

I overclock and have general heat (and dust) issues, so the slightest thing sends me over the edge. Which is why I deliberately restrict RAM so only 10 tasks run at a time.
It helps me, so if you get any kind of issue over the next 24hrs it's a successful easy solution.

I forgot to mention, you were right to suspect RAM being the limitation - a hurdle that has to be jumped over when tasks start, but not while running.
Someone speculated that if 200% RAM could be allocated to Boinc, more tasks would run, but that doesn't pan out. (Yes, I tried...)

I had a similar thought, but couldn't set it to a value over 100 through the GUI. Is there another way?

Not that anyone's found or revealed.
It was said partly in jest, but considering the RAM demand at task-launch compared to what's used when the task runs, there's a case for saying the project started it with their own comical suggestions
