Memory - 1 gig used / 2 gig cached but 7.6 gig free

SYSTEM INFORMATION
OS type and version Raspbian Linux 11
Webmin version 2103

Ironically, looking to get webmin to use MORE memory. Seems inefficient to have nearly 8 gig free.
984 meg used, 1.62 cached, 7.62 gig free.

I would like to improve performance.

Your OS manages memory. I wouldn’t worry about this. Most of what webmin does is merely a web interface and it shouldn’t use too much anyhow.

Edit: Is it possible Raspbian Linux 11 imposes special settings to make sure this runs well on their lower memory units?

Webmin doesn’t need more memory.

But, if you have databases, you can configure bigger query caches and the like to improve performance a bit based on your workload and recommendations of your app developers.

And, Linux does pretty aggressively cache disk access and such, so if you keep using your system, it’ll keep using more memory over time until the buffer cache is nice and full (assuming you have enough data and shared libs on disk to fill it).
