The sole purpose of the pi is not to write kernel log files. I&#x27;m sure if you want to build a piece of hardware &#x2F; software kit that did nothing but write sequentially to a flash drive, that&#x27;d be blazingly fast.<p>But if you want log rolling, filtered output, serial output, non-flash file systems (nfs, etc) and a general purpose computing device where printk is the rarest of rare events (in the lifetime of a task) then you&#x27;re going to lose some of your optimizations.
