Poor SLOG performance after joyent_20170831T155808Z #946
I'm observing poor SLOG write performance after joyent_20170831T155808Z, with both KVM VM and NFS.
Here are tests done with builds from 20170831T155808Z, the next one after that and the latest as of writing this. Something seem to be slowing down this hardware with builds since 20170913T233706Z.
