Re: [NTG-context] Bug: context/mtxrun makes Firefox eat up cpu

I would consider it more constructive to admit the existence of the bug and find a way look into the source code of luametatex, since `context --help` is obviously not a terribly complicated routine to investigate. On Thu, 29 Oct 2020 at 13:56, Taco Hoekwater wrote:

I've just tried chromium which behaves a bit better but still experiences a sudden raise of cpu usage from <10% to >70% during ~1s. I've also noticed that, even without any browser running, each time after I compile a file with `context`, my terminal get stuck for ~1s. So I'm pretty sure this is a context bug, probably caused by unnecessary excessive disk operations or something.

But it seems to be a big problem only on your machine. What hardware are you running on? Is it a Raspberry PI?

Like any TeX-related program, ConTeXt does a fair bit of disk access while starting up, but I haven’t heard of that being an actual problem since the age of single-core CPUs. And it certainly should not have an effect on the CPU usage of any other program (it could affect system responsiveness, though).

Best wishes, Taco
