I face a problem, which was already addressed about 9 months ago by you, more specifically -- timekeeping. In my case the clock is counting 20-30 times slower. It takes roughly 20 seconds for the benchmark to run, however by completion the rumprun clock tells me that only 0.9 seconds had passed. I used different \"time\" functions including gettimeofday() all of them give the same result.\r\n\r\nInvestigation with a test program calling `getttimeofday()` in a busy loop shows that time is \"oscillating\" around a single second. If `sched_yield()` is called inside the loop then time flows normally. Problem is reproducible on all platforms (Xen, hw with KVM or QEMU)."},"comment":{"url":"https://api.github.com/repos/rumpkernel/rumprun/issues/comments/203971874","html_url":"https://github.com/rumpkernel/rumprun/issues/71#issuecomment-203971874","issue_url":"https://api.github.com/repos/rumpkernel/rumprun/issues/71","id":203971874,"user":{"login":"mato","id":190797,"avatar_url":"https://avatars.githubusercontent.com/u/190797?v=3","gravatar_id":"","url":"https://api.github.com/users/mato","html_url":"https://github.com/mato","followers_url":"https://api.github.com/users/mato/followers","following_url":"https://api.github.com/users/mato/following{/other_user}","gists_url":"https://api.github.com/users/mato/gists{/gist_id}","starred_url":"https://api.github.com/users/mato/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mato/subscriptions","organizations_url":"https://api.github.com/users/mato/orgs","repos_url":"https://api.github.com/users/mato/repos","events_url":"https://api.github.com/users/mato/events{/privacy}","received_events_url":"https://api.github.com/users/mato/received_events","type":"User","site_admin":false},"created_at":"2016-03-31T14:48:29Z","updated_at":"2016-03-31T14:48:29Z","body":"/cc Anton Ivanov (@ian7on)"}}
