Heho,
I am running a small setup, where recently the boarder router VMs of a user
caused prolonged and consistent low bandwidth (2-3mb/s) yet high utilization
(many IOPS) disk utilization on the virtualization nodes (more writeup at [1]).
With a bit of digging, we figured out that this was cause

I took this as motivation to do some benchmarks (defaults, noatime, softdep,
noatime+softdep, mfs, mfs+noatime) on a VM with eight cores and 8gb of memory
