On the VM server I issued the command below every eleven minutes:date >> curltest-file; _ top -b -n 1 | sed -n '7,12p' >> curltest-file; _ curl -o /dev/null -s -w"time_total: %{time_total}\\n" https://my.domain.com | perl -pe 'BEGIN {use POSIX;} print strftime("%Y-%m-%d %H:%M:%S ", localtime)' >> curltest-file This gives me the total time for displaying my site on a local machine. It also includes a 'top' command to display which processes are running at each sample. All is saved in a file called curltest-file. I found 7 occurrences in my curltest-file of a time_total larger than 20 seconds. Top however didn't show any significant CPU or IO activity at those sampled times. Further investigations shows me that they are related to a known (gravatar) issue in the Wordpress Jetpack plugin. I didn't include these samples in the average total.If you just use halt_poll_ns or both halt_poll_ns and idle=poll in guest?
I just use kvm.halt_poll_ns=500000 Should I try some different tests? -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
