The Speed of Time

Brendan Gregg

CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. Since instances of both CentOS and Ubuntu were running in parallel, I could collect flame graphs at the same time (same time-of-day traffic mix) and compare them side by side. Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()?

Why OpenStack is like a Crowdfunded Viking Movie

VoltDB

An opening scene involving a traffic jam of Viking boats and a musical number (“Love Can’t Afjord to wait”). 5G expects a latency of 1ms , which considering that the speed of light means the data center can’t be more than 186 miles away, or 93 miles for a round trip, assuming an instant response. Vikings fight zombies.
