CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. Note that Ubuntu also has a frame to show entry into vDSO (virtual dynamic shared object). Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()? What on Earth is Ubuntu doing that results in 30% higher CPU time!? ## 1.
