Sure but how to benchmark? Just create a file with 32 values and create
2 files (this but be the avg of network interfaces) may be it is just 1.5.

And then update both each second and look at the disk i/o? Or how did
you imagine this. I think it makes no sense to compare 32 values agains
32 files as most VMs won't have 32 nics.
