extension causes UI slowdown

Reported by realgran...@gmail.com, Mar 25 2016 
UserAgent: Mozilla/5.0 (X11; CrOS x86_64 7834.60.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.95 Safari/537.36
Platform: 7834.60.0 (Official Build) stable-channel falco

Steps to reproduce the problem:
1. disable swap entirely
2. work
3. notice lags and hiccups all over chromebook

What is the expected behavior?
as no ram is compressed or moved around - no lags at all (used to be)

What went wrong?
chromebook UI is laggy and unresponsive

Did this work before? Yes a few previous releases before

Chrome version: 49.0.2623.95  Channel: stable
OS Version: 7834.60.0
Flash Version: Shockwave Flash 21.0 r0

I used to disable the swap to increase performance as chrome just threw away old tabs/thing unused. Now it does not help, even with swap disabled I see massive lags in the UI, even to close the tab. When swap is enabled it is better at first, but then becomes mush worse

All the UI issues were caused by an extension - I disabled all extensions and it wend back to normal. You can close the issue if it is okay for extensions to cause such slow-downs, or the issue may be renamed to "extension causes UI slowdown" and I can track which one

Hi

It is much better with latest update, but still the extension

https://chrome.google.com/webstore/detail/plottico-tracker-pro/hjfkpgknlchgabgfhknaedgodmnhieep?hl=ru

is unusable on a chromebook (I am the developer of this extension and I develop it ON a chromebook, but using a crouton chromium installation, as chrome OS' browser hangs and is generally very slow). Try to enable/disable it - the UI will just freeze for several seconds, and during the normal use it will periodically freeze

I can make a reproducer extension that will crash the chromebook using just some console.log() and message postings.
