Works well. To make it better have it open the tabs without loading the content or maybe stop loading or unload the tab after loading the page title, then when the user clicks on the tab, load the tab. This will reduce cpu and memory load.

One way to achieve the above is to use Open Bookmarks Slowly together with the "Auto Tab Discard" extension. In Auto Tab Discard options, enable "Discard all newly opened inactive tabs after they get loaded". This will unload the newly opened tabs from memory, and prevent the computer slowing down due to RAM being used up by many open tabs. When you click on the "discraded" tabs (really unloaded), they then load.
