It does feel much snappier than before so the pain was worth it in the end. :) On my VirtualBox machine I have a feeling that it is spending more time doing TLB shootdowns than before on /some/ workloads. Running cvs update on a cgd(4) is definitely slower than before. Randomly breaking into ddb shows that it's always spinning in pmap_tlb_shootnow() rather than waiting for disk or net I/O which I would expect. I couldn't reproduce the problem on bare metal so it might just be the usual VirtualBox jank. -Tobias
