I wouldn't bother. The reason it's slower than the generic kernel is that the lowlatency kernel prioritizes AUDIO, nothing else. Therefore, everything else is slower as a result of the audio taking a higher priority. That's not a bug, that's actually a feature.

The generic kernel exists for general purpose, the lowlatency kernel, while it works for general use, is definitely configured to prioritize lowlatency audio.

Also, PLEASE make sure you're specifying 18.04, 19.04, or 19.10. The version numbers are the year (19) and the month (04 or 10) formatted as yy.mm. Leaving out those digits doesn't help with diagnosing issues or configurations.

I hope that helps you understand.
