Today we’re excited to announce that we’ve launched yet another POP location to help further supercharge our network’s content delivery speeds. Although both countries are relatively close to one another, they are separated by a distance of approximately 500km, which adds up in terms of latency. penetration rate.

bpftrace is a new open source tracer for Linux for analyzing production performance problems and troubleshooting software. Linux already has many performance tools, but these are often counter-based and have limited visibility.

eBPF was created by Alexei Starovoitov while at PLUMgrid (he's now at Facebook) as a generic in-kernel virtual machine, with software defined networks as the primary use case. Back then I could already tell if disks were seeking by interpreting iostat(1) output: seeing high disk latency but small I/O. eBPF does more.

Electricity used by servers doubled between 2000 and 2005 (and has continued growing ever since) from 12 billion to 23 billion kilowatt hours. Each HTTP request that is required for the page needs to travel over the network and in turn this consumes energy on both the server and client. It’s a win-win all round! Show me the money!
