If you go to a lot of flash sites (hard to avoid) with Chrome / Chromium then that's a lot of flash plugin that can leak memory and potentially cause issues even after Chromium is closed. Try a day with a maximum of 10 tabs in on browser (and one browser window) and see if you still get performance issues. Also check if you have ubuntuone-syncd running. Ubuntu 11.10 may add this back in at startup as part of the change of desktop manager (LightDM) Thank you. -- <http://uk.linkedin.com/in/johnstevenson247>| John Stevenson<http://uk.linkedin.com/in/johnstevenson247>| Public calendar <http://john.jr0cket.co.uk/public-calendar> | @JR0cket<http://http//twitter.com/#%21/JR0cket> | gplus.to/JR0cket | Tech websites <http://jr0cket.co.uk/> | Tech blog <http://jr0cket.com/> | Lean Agile Blog <http://leanagilemachine.com/>
