Linux early boot memory allocator slashed from 268 seconds to 50ms
Original: Linux's Early Boot-Time Physical Memory Allocator Big Speed-Up: ~268s to ~50ms
The Linux kernel's memblock, the physical memory allocator used during early boot, has been dramatically optimised in the upcoming 7.4 cycle, cutting its initialisation time from roughly 268 seconds to about 50 milliseconds. The change, reported by Phoronix, drew attention from kernel developers and systems enthusiasts discussing the scale of the improvement and its impact on boot times for large-memory servers.
Why now: A change cutting early boot initialisation from minutes to milliseconds is a striking engineering result for anyone running large-memory Linux machines.
