Benchmarking Ubuntu's Low-Latency Kernel & Liquorix Post-Meltdown

Written by Michael Larabel in Software on 14 January 2018. Page 5 of 5. 35 Comments

With a few Linux gaming benchmarks, the Liquorix kernel was significantly slower than the others while low-latency and generic kernels were about tied.

Here's a look at all the numbers overall:

Overall, while the Liquorix kernel won in a number of the benchmarks, in the tests where it wasn't leading, it tended to lose significantly. As you can see, Liquorix had a sea of red: the most losses. The generic Linux 4.14.13 had 15 wins (35%), the Linux 4.13 generic kernel 10 wins (23%), the Liquorix kernel with 9 wins, and then the low-latency kernel with just 8 wins. But when it came to losses, Liquorix finished last in 21 of the tests while low-latency lost in 9, the Linux 4.13 generic kernel lost 8, and the Linux 4.14 generic kernel lost in four of the tests.
