CPU usage is real high

[krasnoukhov]

I'm not sure why and I'm also not sure if this is specific to OS X, but I'm getting a really high CPU usage.

When loading:

When already loaded and idle:

Any ideas?

[Sergio-Muriel]

Just pulled a fix for that, cpu looks fine now. I think it was due to the guibackgrroud jobs.

[krasnoukhov]

I'm wondering which version of perl are you using and how many subscriptions/items do you have? The fact is, issue still persists :person_frowning:

[Sergio-Muriel]

I use perl 5.18. I don't think the number of subscription items matters as the periodic jobs only update the count numbers of the labels, and the right list.

I think you may have high cpu usage when loading (still working on that), but did you have it on iddle too?

If true, maybe you can help me debug it (cause i don't have that issue here)? Just comenting the lines 61/62 on TheoldReader/GuiBackground.pm (to disable the background jobs), so i can see if it is due to the background jobs, or to the frontend loop.

Thank you!

[krasnoukhov]

You're right – commenting the lines you've mentioned reduces CPU usage to, like, zero. I hope that helps!

[Sergio-Muriel]

I made some updates with the treads system to close them properly, so i think there is will be "less?" memory leaks and cpu usage.

[krasnoukhov]

Thanks for the effort, this is really apprecicated. However, still seeing high usage:

Sorry :(

[Sergio-Muriel]

Hi again. Could you test it again but:

• remove log file first
• run with -debug option: $ ./gui.pl -debug

If the cpu is still high, can you send me the log file to check for times on loops?

[krasnoukhov]

Sure, here you go:

[Sergio-Muriel]

So you didnt notice any improvment at all?

[krasnoukhov]

Looks like CPU is good when idle, but still 200-300% when loading :(

[Sergio-Muriel]

Great, the fixes was for the iddle task. Lets improve loading task!

[krasnoukhov]

Nice! Ping me anytime to test. Hope you can do it!

[Sergio-Muriel]

Great, then. Maybe you could re pull and rerun with -debug option, so i can check the new log commands i just put :)

[krasnoukhov]

Strange, it does not seem to log anything other than

02/22/2015 19:07:32 BG: DONE thread bg ! 
02/22/2015 19:07:33 GUI: done

[Sergio-Muriel]

Try with -debug option

[Sergio-Muriel]

Just pushed a few changes, can't think i do much more for cpu load.

[Sergio-Muriel]

I removed the use of iconv, waiting for another tip to display utf8 characters on Curses::UI

[krasnoukhov]

Well, thanks for trying. Feel free to close this one if that's all you can do

[Sergio-Muriel]

Finally understoud was you told me about the number of subscription you have.

How much subscriptions do you have? To get labels, i fetch them from subscription_list, and that could be long if you have a lot of subscriptions.

[krasnoukhov]

I don't think a lot, it's around 150.

[Sergio-Muriel]
