The Speed of Time

Brendan Gregg

Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()? Aftermath I provided details to AWS and Canonical, and then moved onto the other performance issues as part of the migration. I also shared setting the clocksource in my talks and in my 2015 [Linux tunables] post.
