Client: Keybase Using lots of CPU

[koehn]

Keybase GUI Version: 1.0.16-20160803190018+268b023
macOS 10.12 Beta (16A284a)

App routinely uses about 75% CPU as reported in Activity Monitor.

Hi, we don't support Sierra yet, I'd bet the CPU usage is being caused by something being broken there.

[mikz]

The same here. Given it is RC1 now it might be good time to start taking a look.

[notahat]

Seeing the same thing on the actual release of 10.12.

If poll() is being used, a possible candidate is: https://daniel.haxx.se/blog/2016/10/11/poll-on-mac-10-12-is-broken/

Yep. This is where it hangs in the logs:

110450 2016-10-18T11:43:38.610429 ▶ [DEBU keybase main.go:456] 029 + Enter ListenLoop()

[bleys]

poll() bug is confirmed fixed in macOS 10.12.2. Close?

Promisingly, Keybase avg energy impact (0.61 as I look now) is just above Finder and just below iStat Menus Status. However, a Keybase Helper process is my #1 CPU time user, clocking over an hour in a day. This is without me using Keybase at all in that time. Seems like it's still overactive in the background, even without poll bugs.

Thanks for the report. CC: @keybase/react-hackers

Yeah our animated gifs are still resource intensive...

We did a workaround here:

Will be available in next public build.

Still seen high CPU use on Linux 4.4.0-112-generic #135-Ubuntu SMP Fri Jan 19 11:48:36 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

@dnickerson do a keybase log send if you want us to look into it. It's almost certainly a different issue from the above BTW

@maxtaco chiming in, my log id is 5b1fd4f9cbc9c996dd07f81c

@joar this an electron bug, @heronhaye knows more about it.

[heronhaye]

@joar on linux? Should be fixed in the next release, but if you like you can try out a nightly at https://keybase.io/docs/linux-user-guide#nightly-builds and let us know if it is better.
