UPPAK Acronym?

Timothy_Hall — Tue, 20 Jan 2026 14:20:32 GMT

So I always thought that UPPAK stood for Userspace Performance PAcK. But now it looks like sk184493: Core Dump Space Limit Resets to 30000MB on Quantum Force Appliances and LightSpeed Appliances after Reboot states that UPPAK stands for "Universal Packet Processing Acceleration Kit", is that correct? Guess I gotta ask this now too, what does KPPAK stand for?

I always thought as well it stood for userspace performance pack. But that sk does indicate new acronym...lets see if someone from CP can clarify.

It's not actually new. Packet Processing Acceleration Kit is the name which was used internally back when SecureXL was introduced. The license was called "Performance Pack", so everybody called it that, and the original initialism was mostly forgotten.

I'm a little surprised the U is for "Universal" rather than "User-mode", since it seems less universal than KPPAK.

From https://support.checkpoint.com/results/sk/sk153832 - UPPAK" stands for "User Space Performance Pack".

I will raise an issue with the documentation owners

Should be fixed now in the reported SK.
