big performance gap between native, tart and lima (vz)

### Description

While testing around I noticed that running `sysbench cpu --threads=4 --time=10 run` will produce big performance gaps between native (m1 pro / m4 pro), lima (ubuntu) and tart(macOS). I tried to find the reason but nothing so far, both tart and lima using `vz`.

not sure its that a lima issue but I would be happy to provide more debug details if needed.
