I think my computer might be running slow.
HP Z-Workstation
I am running Kubuntu 24.04.2 LTS (Noble Numbat).
The CPU is 12th Gen Intel(R) Core™ i7-12700K with 32gig of ram no gpu
I still have a little time on my warranty.

Hey @Fred here’s some ideas we got discussing this on the Discord server. If you want to see the conversation itself on the Discord then you can go here.
These steps are just a guide with some ideas, not a guaranteed fix. You also probably wont need to do everything.
Basic testing that wont require stress testing.
Why? If the live session feels fine, the slowdown lives in your installed system. If not, it’s likely hardware.
htop
→ sort by CPU and Memory.Why? Kubuntu ships a sane default set, but any distro can get bogged down by extras over time.
mesa
and intel-media-driver
(sudo apt update && sudo apt upgrade
).Why? The Intel iGPU is plenty fast, but driver hiccups or fancy effects can still cause jank.
If the answer isnt found there then might need to do some stress testing.
stress-ng
/ phoronix-test-suite
/ s-tui
/ Hardinfo2
).Why? This quickly confirms whether the silicon itself is healthy.
sensors
, Psensor, or btop
and display temps & clocks.Why? High temps or clock drops mean the cooler, thermal paste, or airflow needs attention—and you can still claim on warranty.
iotop -oPa
(or enable iowait in btop
).smartctl -a /dev/nvme0
(or /dev/sdX
) to verify drive health.Why? Storage stalls often feel like “the whole system is slow”.
Why? Bad or down-clocked RAM can both crash and drag a system’s pace.
Why? Hard evidence speeds up an RMA and tries to avoid the “works fine in our lab” response.
Thank you for the comprehensive response.
