kata-irc-bot | <xwlpt> Hi all: we are testing kata, we launched a webserver, which runs by runc and kata runtime , then use the same qps to test the performance. They have the same cpu/memor request and limit. From the test result, the cpu usage is lower for webserver runs on kata runtime than webserver runs on runc. We’d think this kind of result doesn’t reasonable. So is there anything that may related with this of kata? | 10:33 |

davidgiluk | xwipt: How are you measuring the cpu usage? | 10:54 |
kata-irc-bot | <james.o.hunt> @xwlpt - you might want to read https://github.com/kata-containers/documentation/blob/master/design/vcpu-handling.md (and maybe look at https://github.com/kata-containers/tests/tree/master/metrics). | 11:00 |

kata-irc-bot | <xwlpt> @james.o.hunt Thanks, will take a look. | 12:30 |
kata-irc-bot | <xwlpt> @james.o.hunt I think vcpu not impact the performance, because the container has been configured with cpu/memory cgroup. | 12:32 |
