Excessive CPU usage

[m4rcu5]

Hi,

I reported this in #117, but as that one is currently closed, lets move it here.

When having the plugin installed, and no project loaded, the CPU seems to be excessively used. The culprit is in one of the plugin_host threads of sublime_text.
Tracing the thread, it shows lots of activity in the virtual env, lots of the Python modules are accessed, as well as the package configuration files.

This makes my CPU usage on my i5 laptop spikes 12-25%.

I'll start to check this again...
is this happening even if you open ST and let it there without doing nothing?

What is your O.S?

Hi @gepd,

I closed all files and restarted Sublime, it still uses the same amount of cpu. Letting it sit for a while does not change anything either.
Looking at the strace, it seems to do the same action every 2 seconds.

Thanks!

mmm That so weird, I don't have any code in background like you mentioned. Yesterday I tested this with ProcessExplorer in Windows and nothing was in background, so with my configuration there is not problem.

I'll try to replicate your machine to see if can get the same results; Please tell me your O.S, ST version and plugins installed

Sorry, I should have added that before.

I have dumped the complete strace in a gist.

The following plugins are installed (pulled from the profiler):

I am running Gentoo with Sublime Build 3126 on the stable channel.

[gepd]

I've been the last two nights trying to install gentoo, but I always find a problem. The last problem was with the VMware image from osboxes, it runs well on my machine but I never finded the terminal or a way to install a package.

So is it possible you can let me debug the plugin from your machine? with teamviewer or something similar?

[m4rcu5]

Sorry, maybe I should have told that Gentoo is not the most user friendly distro. By default, it comes with nothing :)

I did some more testing. In the end it is a combination of plugins triggering this;
The Package Sync plugin scans the Packages folder on a regular basis, and as Deviot installs a complete penv environment there, this has not exponentially grown in size/amount of files. Causing the scan to use way more CPU power..
I mitigated it by excluding the Deviot folder.

One more thing I noticed during this test;
The Package Sync plugin syncs the Package configuration to my other machines (via Dropbox), but the Deviot preferences also contain the installed state and last_check_update state, which are local to the machine. This stops a PlatformIO installation on the other machines.

[gepd]

Thanks for the report, I will think how to solve this, maybe a new file with the last_check_update information could help, so you can exclude only that file.

I'll let you know when this is available to test

[gepd]

I've changed the way to store the preferences. You can exclude the file located in Packages/Users/Deviot/deviot.ini

Please install the develop branch and let me know if it's working for you.
