A few years ago, we decided to address this complexity by spinning up a new initiative, and eventually a new team, to move the complex handling of user and device authentication, and various security protocols and tokens, to the edge of the network, managed by a set of centralized services, and a single team.

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.

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.

For example, iostat(1), or a monitoring agent, may tell you your average disk latency, but not the distribution of this latency. For smaller environments, it can be of more use helping eliminate latency outliers. Kernel dynamic tracing of read() bytes bpftrace -e 'kretprobe:vfs_read { @bytes = lhist(retval, 0, 2000, 200) }'.

Modern, asynchronous network APIs that dramatically improve performance in some situations. For heavily latency-sensitive use-cases like WebXR, this is a critical component in delivering a good experience. CSS color().

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!
