High memory usage is something most modern tabbed browser are plagued with, we have shared the excellent FireMin add-on for Firefox to tame the situation, and here is an equivalent for Google Chrome.
Working on the same concept as BarTab for Firefox; The Great Suspender for Google Chrome makes unused tabs inactive saving computing resources. The addon dramatically reduced the memory usage to 1.5x. Tab suspension not only saves memory, but also aids in a snappier browsing experience as inactive tabs do not consume other computing resources.
