Home router latency (Linksys E1550) - quick test.

Quick, take a guess, what's the first hop latency to your home wireless router?

Below 1ms, right? Yeah, you wish!

Below are results from a quick test on my home router (Linksys E1550). Some lessons learned:

  • 3-8ms median
  • very different latency tails on different channels (1,6,11)
  • running in mixed mode helps tame the long tails (do it, if you can)
  • all tests on 2.4Ghz, unfortunately E1550 can't do 5Ghz

# Usage: git semver-tags [-p|--pre]
#
# Lists semver tags in the repository in order from newest to oldest.
#
# Useful for e.g. programmatically finding the latest release tag:
# `git semver-tags | head -n 1`.
#
# Tag names must be valid according to the SemVer 1.0.0 specification
