CPU usage on Mac OS Catalina, Brave: 1.13.82, Chromium: 85.0.4183.83

after about 5 minutes Buttercup extension became unaccessible, its process sucks 100% of CPU:

after killing the process and reloading the extension it follows the same behavior again and again:

Thanks @tourtools - The reason for this is the fact that Buttercup core (5.2.1) has a very dramatic memory leak in its auto-update function, which causes large amounts of objects to be addressed and tied-up in permanent references of each other, so GC never takes care of them.

I'm currently addressing this in the core..

The base issue will be dealt with here: buttercup/buttercup-core#282

[tourtools]

thanks @perry-mitchell for the prompt response, I'll follow the core issue 282

So it seems like the issue is solved for me, though I haven't tested for many hours. The memory and CPU consumption is far better than it was, and I've fixed a number of poorly-performing vault item lookups in the core library. I'm about to do a release - v2.22.0.

tested with Brave with the new plugin/core v 2.23.0 and the results are quite the same, maybe it takes a little bit more time to get stuck but after a while the process reach the 100% of CPU and the plugin became unavailable:

FYI

Performance still bad for me in 2.23.0 (i.e. Vivaldi) but it's hit and miss

Will keep an eye on CPU next time as I imagine that may explain the hit and miss nature

I think this issue or https://github.com/buttercup/buttercup-browser-extension/issues/368 should be reopened

When CPU is high (i.e. >10%) the popup is delayed:

Hope this helps

Sincerely

@ldexterldesign Good point, I've reopened that issue.
