The processor and memory are very slow. Compiling the ixgbe network card driver takes 10 minutes. The maximum read speed of DDR4 2133 SODIMM is 742 MB / sec. Custom motherboard with Atom Denverton C3538 processor, quad cores 2.1 GHz. SODIMM module: Crucial DDR4 8Gb 2400MHz CT8G4SFS824A. BIOS: coreboot 4.9 + intel FSP + seabios. WD Blue WDS250G2B0B 250GB, M.2 2280, SATA III Hard Drive. Debian 7 (Linux version 3.2.0-4-amd64 ( debian-kernel@lists.debian.org) (gcc version 4.6.3 (Debian 4.6.3-14) ) #1 SMP Debian 3.2.96-2).
Why the slow operation of the processor and memory is possible? What settings can be changed in Intel FSP and coreboot to speed up the processor and memory?
