Recommendations for optimizing system performance

Not sure if I should really do anything at all but it doesn’t hurt to ask.
This is a custom-built desktop with no discrete graphics. Specs pasted below.

Will I benefit from a zen kernel and/or system tweaks?

I run Windows 10 in VirtualBox. In the VM, I run light apps such as Microsoft Word.
Sometimes, on the host machine, I convert videos to a different format, using Handbrake.
Otherwise, I don’t do anything heavy. And I am not a gamer.
My memory usage is usually between 40% and 60% of my 16 Gb RAM.
Should I just leave things as is, or tweak?

You can try/use the zen kernel, the gains are more noticeable on older cpus under heavy load and I believe it has the esync patch integrated for wine and support for anbox


The golden rule is “tweak it until it breaks, then tweak it a little bit less”. :grin:

I would start with inxi command using -z to filter out private information when you post on internet. But that is probably my paranoia talking. :wink:

Anyway, with 40-60% memory used I would consider enabling swap. You have ssd disk so that could help in some edge conditions when you decide you want to run something fancy parallel to virtualbox.

It is also important to consider how is your filesystem split into those 2 drives. There are some tweaks for specific applications as well. For example I like this firefox on RAM. It helps a lot if you have your home directory on HDD.
