Is your VM under memory pressure?
I don't think so. The host has 128 GB of memory, and even the
pre-emptive kernel caching doesn't come close to filling it:
me@host:~$ free
total used free shared buffers cached
Mem: 132043960 1742480 130301480 0 84628 826040
-/+ buffers/cache: 831812 131212148
Swap: 1048568 0 1048568
My /tmp should be physical disk in both cases. To be thorough, I also
ran the test while writing the output file to /, and got the same
results (5.7 MB/s on guest, 144 MB/s on host).
Your guest is only assigned 256MB though.
