Can you please comment on the overhead QEMU brings in terms of latency

I am running a highly latency sensitive application on my VMs and I see
some degradation in performance when running 2 QEMU processes on a
single core, or even when I run 1 QEMU process on a single core without
a dedicated affinity and RT priority to the QEMU process.
Can I make the QEMU lighter to be able to run 2,3 or more QEMUs on a
single core? Is it matter of XML configuration / affinity / priority or
