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

Originally posted by Linuxxx View PostHere's how one can achieve real smoothness:
- Use openSUSE Tumbleweed, since it contains the best Linux Kernel config by default. (250Hz tick timer, PREEMPT enabled)
- Use the deadline İO scheduler.
- Use the 'performance' governor.
- Additionally, if stuck on İntel, make sure to set the 'performance-bias' to '0'!
Now enjoy your silky-smooth Linux experience!
I am trying to improve performance on my server. I have a few processes that need low jitter (less than 10ms variance). I have a load average of 4 maximum on an i7-920 (4 physical cores, 8 with HT).
I'll have to check how many of these settings are used in Arch by default...

Why not 1000hz?

Nowadays I just run Ubuntu 18.04 LTS with the "lowlatency" kernel. (Which does have a 1000 Hz timer tick, by the way.)

The Linux kernel's CONFIG_HZ option can modify the balance between system throughput and latency. In this article, we explore its effects on KVM.
Seems 1000hz isn't necessarily the lowest latency, for example.

After reading these benchmarks I realize I understand even less about what CONFIG_HZ actually does:

Overall, 1000Hz nets better minimum framerates.
...
It is advisable to pick 1000Hz over 100Hz or 250Hz in order to receive a small but tangible minimum framerate improvement while gaming.

So, 1000 Hz is clearly the best, no matter how you look at it!
