Just a quick CPU benchmark with Phoronix test suite, comparing -cpu qemu64 and -cpu host (on Xeon E3-1241v3, 4vCPU/4GB virtuals).

Note: single run (fire & forget), virtual machines on the same physical hardware and benchmarks run simultaneously. YMMV.

Benchmark qemu64 host Higher/Lower better?

No wonder why UpCloud changed their parameters, -host usually wins…
