My Lenovo x230 was beginning to struggle with Windows 10. It would boot up in seconds but something was always consuming a quarter of the processor and browsing was sluggish.
Having since replaced Windows with #Debian #Linux and Chrome with Firefox the machine boots just as fast and feels snappy, even when browsing!
What's more, no longer does the processor get swamped and browsing barely puts more than 1.25 load.
Amazing!
