Re: Aquamacs nightly takes a lot of CPU

[David Reitter]

Hi Hans,

Thank you. I am aware of a problem where Aquamacs will not react for a few seconds after starting up. This has been difficult to locate. (Aquamacs -q doesn’t reproduce this for me, but I couldn’t identify any settings that cause it.)

I believe that this may be related with the issue I've found where using
emacsclient/server can trigger soaking up a ton of CPU.

But I haven't found a way to isolate this issue yet.

Hans,

I have just experienced 100% CPU load myself.
When you see this, could you take a “spin dump” using Activity Monitor (click on Aquamacs entry, then select gears icon and “spin dump”)? I would like to compare notes...

I am getting this as well.  Spin dump from 15Mar16 nightly is here: https://dl.dropboxusercontent.com/u/47769639/Aquamacs3.3_15Mar16_nightly.txt

I wonder if this is an issue with El Capitan.  I'm now having troubles with the Thunderbird email program where it starts chewing up 100% CPU (or even more, as reported by top!).

[Iliya Lefterov]

Hi Robert,

what is the machine you are working on - BookPro, iMac, or MacPro? It clearly happens with Aquamacs, from time to time on older BookPro(s), but not on MacPro...

have a nice evening

It's happening to me on my MacBook Pro.  Now that it's happening on Thunderbird, too, I'm starting to wonder if Apple messed something up in El Capitan.  This never happened to me on Yosemite.

But then, it's never happening to me on Aquamacs 3.2 -- I had to revert to that.

Best,

I had that the other day when I installed a nighty and had to revert to 3.2 too.

There are a few references to a CPU load problem with El Capitan, but no technical description. Similar reports are out there for past versions of the operating system.

Does the console show anything when the problem happens?

hm... the latest nighties are working slower on my MacBook Pro, too...

have to take a closer look; never seen this with Emacs 25.0.50...

best,

Can you show a benchmark?
I’m not seeing that, but I tend to run a version compiled locally.

What I am seeing is a strange delay upon initial startup.

　I just installed 11.4 and even AE3.2 is making my cpu work like crazy...

I am still getting pegged CPU and unresponsive input from the 29Mar image.  I have to kill Aquamacs from Activity Monitor to get out of it.

FWIW, I have an image from 15Feb that works fine.  Something obviously has changed since then.

Let me know if there is something you would like me to do to help debug this.
