I know it's probably really early to ask this, but do you have a rough estimate of when the power usage improvements will happen? Battery life is the main thing stopping me from using Firefox more, so I'm really looking forward to this being fixed.
- agumonkey 8y agoI had a ~power related issue using Quantum. It "killed" my cpu (temp rising by 10s of degrees so fast I didn't have time to throttle before kernel thermal shutdown). I guess it's so parallel and so gpu intensive that my whole system goes into fever. ps: a x201 core i5 520m
- mort96 8y agoWhat? Your system doesn't handle running at max CPU and GPU usahe even for what I presume is seconds before thermal shutdown? That seems like an extremely serious issue with your system.
- agumonkey 8y agoAll I can tell is that ffx quantum is the only program that triggers that behavior. And it's not seconds it's maybe one second. 70-80-90 off.
- DiabloD3 8y agoClean your heatsink out, and also consider replacing the heatsink paste: that CPU is so old, its entirely possible a cheap thermal pad is no longer usable (commonly used on laptops and stock desktop HSFs).
- agumonkey 8y agoDoesn't matter, I burn the cpu with multiple gcc builds and it doesn't rise the same. I had thermal shutdowns it can happen, but not like ffx quantum.
- pcwalton 8y agoI'm going to guess your problem is not CPU related, but rather a hardware issue relating to other hardware that Firefox uses (GPU, audio, …) Firefox spends most of its time idling in event loops; it's not a batch job like a compiler.
- agumonkey 8y agoNote that I'm not blaming ffx, just witnessing something weird and wondering if it's due to using rust parallelism in ways not done through the usual cpp libs.
- pcwalton 8y agoVery doubtful. The only thing I could think of that might conceivably cause similar symptoms would be AVX2, but none of our shipping Rust code uses that.
- agumonkey 8y agoOdd then. I wasn't even using a specific webpage, just loading the previous session (~20tabs of average intensiveness). Chromium has the same kind of session and it never causes similar heat spikes. Anyway I'll try to reproduce it even though it's not pleasing to overheat like that.
