ultrafast
Beyond merely rapid
Ultrafast describes something extremely fast, often at the limits of what's measurable or perceivable.
The term appears frequently in technical contexts—ultrafast lasers pulse in femtoseconds, ultrafast charging promises full batteries in minutes.
In marketing, ultrafast often just means faster than competitors: ultrafast broadband, ultrafast delivery.
