The Great Suspender

Chrome OS computers are built on the thin client model. Relatively modest hardware & most applications running in the Chrome browser keeps prices down. Frequently, this means a large number of browser tabs open, & lag is likely.

Typical solution to lag is to start closing browser tabs — & then re-open them later, when required. A better solution would be to keep all tabs open, but reduce system load by temporarily suspending i/o & processing, apart from the tab in active use.

Enter The Great Suspender extension from suspensionlabs. Default mode, is as described above: tabs which are open, but not in active use, are suspended, but can be restarted with a click.

Options include:
● delay before tabs are automatically suspended
● suspend active tab
● never suspend specified sites
● suspend all tabs, apart from the active tab, now
● unsuspend all tabs

No mention is made in the Google Chrome OS Web Store, but judging from the message which has just appeared in one of my suspended tabs:
“Does this extension make you happy?”
