Why jitter matters more than a single fast number
Most DNS marketing leads with a headline speed. For gaming, that's the wrong number to chase. A
resolver that is usually fast but occasionally spikes will produce the exact moment you notice —
a stall right as your launcher tries to connect at the start of a session, or a patch server
lookup that hangs for a second while everyone else in your party has already started downloading.
Jitter is the variation between lookups — essentially, how consistent a resolver
is from one query to the next. A resolver with low jitter gives you roughly the same short delay
every time, which is far less noticeable than an occasional long one. When comparing resolvers on
the benchmark page, weight jitter and reliability alongside the
median, not just whichever number is smallest.
