Tiny Suspender has two hibernation mode. The default one is pretty similar with The Great Suspender in which it replaces the page with a special "suspension" page loaded from the extension assets. Chrome actually run these "suspended" page under a single extension process, so if you have 50 suspended tabs, they actually run under a single Tiny Suspender extension process, which typically consume ~30-60mb of memory (sometime more, sometime less. Not sure why) on osx. The other mode is experimental and can be enabled from settings. It uses the experimental Chrome tab discard API. This API has some limitations, and I never actually measure the actual memory saving under this mode, but if what chrome dev saying is true, it could potentially save even more memory.
