So the VMs have very different configurations then?

Have you tried giving the 2 VMs equal resources?

Why wouldn't you expect a virtual machine with less vCPUs and less
memory to perform slower?

The rm command might not get the best benchmark to to understand what
is going on. Have you considered testing a microbenchmark like iozone?

What is your disk backend and is it the same for each? It is a shared
directory or are you creating/copying the same directory to each
machine for the test?
