One Of Clear Linux's Kernel Patches To Help With Boot Time Proposed For Upstreaming
Besides Clear Linux delivering often leading x86_64 Linux performance at run-time, when it comes to boot performance it has also been at the forefront -- in some configurations, can boot in 300 ms. Intel has invested significantly in ensuring Clear Linux boots as fast as possible for when running in the cloud or on containers in order to respond to increased demand as quickly as possible as well as for use-cases like Clear Linux within automobiles where they need to get automobile cameras active within two seconds of power on. One of their many kernel patches could be on its way to the mainline kernel.
