%RUN / utilization is closest to what you will see in the guest, if one vCPU is capped but others are not, adding more vCPUs might not help if the application(s) are single / low threaded. 370% usage on 4 vCPUs should be more than 50% in guest utilization, unless the CPU has a very wide NF / max TB span and nothing else is running on that host, maybe it is also doing lots of IO (charged via %SYS to vmx)? Can you limit 'l' the GID in addition to expanding it and pastebin the output?
