The Speed of Time

Brendan Gregg

Colleagues/Internet I love using [Linux performance tools]. But I also love solving issues quickly, and sometimes that means just asking colleagues or searching the Internet. Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()? Microbenchmark os::javaTimeMillis() on both systems.

SpaceX Spending $10 Billion to Make the Internet 20ms Faster

MachMetrics

Elon Musk’s need for speed. A lot of coverage on this project is centered (rightfully) around the potential of this project to deliver fast internet to underdeveloped nations at a minimal cost. This ultimately guides us to one conclusion: Speed is incredibly important. Starlink’s Goal: Reduce Internet Latency.
