FF 45.x and CPU spikes
Dariusz Piatkowski:
Hi Everyone,
I thought I would provide a quick update on having deployed that /NOHLT option and observing the impact on my system.
In general, the previous issues I would run into with FF have been significantly reduced. While I do not know much about the actual logic that /NOHLT implements, I have to say that even when the CPU spikes occur (and they still do, however much less frequently) the application, and the system overall remain very responsive.
More specifically:
1) GMAIL - spikes still occur when the browser TAB has focus, but once removed (switch to another app or virtual desktop) they go away
2) SYSTEM - it used to be that whatever application was causing spikes would continue to cause them regardless of how much time has passed, that is no longer the case, I have now observed a consistent result where the CPU spikes taper off and the load across all CPU cores falls down to nearly zero, I mean literally a standard 2-4% utilization
I cannot explain it any better than that. It is just a "seat of the pants" feeling, or as we say in car racing: "butt meter" tells me the ride is faster! ;D
Therefore, for now I'm leaving that setting in place, unless and until my hardware changes and this needs to be re-visited, or someone spells out the reason why this is a bad idea.

Have you people tested a new profile? A lot of these problems are likely cruft in the profile.
My SeaMonkey wouldn't display my bitbucket pages correctly (left sidebar just gray areas) and Firefox, while displaying them, used a lot of CPU and was very slow. Tried a new SM profile and the pages loaded fine with close to no CPU usage.

just for a feedback, a new profile hasn't changed those page display problems in my case, but my personal idea is that FF 45.9 is still good for browsing the most of other pages, of course looking for an actual QT5 browser coming.
Furthermore, if I'm allowed to ask this question inside this thread, could someone tell whay I cannot get the sound of youtube videos? They run without audio also whit their volume gadget at 100%
If it depends by the H264 (Open264) plugin, the situation in my FF is the one shown in the image, like it is there but hasn't been installed for some reason.
Thank you

Yes, it really depends on why the CPU is peaking. I'm also using a newer build, which I've had problems uploading.
Even with the new browser, I expect that people will run both in parallel for quite a while. The new browser is going to be missing support for add-ons and it'll take a while to migrate things like passwords.

Actually that plugin doesn't do anything on our browser and is for video conferencing. The H264 playback is handled by the FFmpeg libs.
The sound widget on Youtube is broken on our port. I'd suggest downloading PMUniMix from Hobbes and playing with the various volume sliders. I had one box where the front speakers needed to be turned up to hear Youtube audio.
