@ljs@mastodonapp.uk which linker are you using (GNU LD or gold or LLVM's LLD?), and is this an incremental build or a full build with all the config options? a large part of the kernel build is "link the whole kernel, repeatedly, because kallsyms is a big hack", and if you do that with GNU LD, it's gonna be single-threaded and take a long time, so a client-style CPU will have an advantage over a workstation-style CPU...
