I suspect that L3 impacts performance a lot. I dabbled in running a Windows VM with a GPU passthrough, and I had to spend a lot of time to properly pin virtual cores to physical ones so that CPU caches are utilized properly, as I suspected that it was the reason for decreased performance. I managed to get only L1 and L2 to be utilized properly and it somewhat helped, but L3 was still underutilized due to double-scheduling in both Win VM and Linux hypervisor. Even the basic OS shell suffered from lags, not to mention games.
