So I jumped ship from Windows to Kubuntu last night, and It’s mostly been pretty good. However my general performance of the computer has been abysmal. Like it takes upwards of 5 seconds to open anything. All of my hardware seems to be running at max speeds, so I have no idea why it would be so sluggish? It’s as if I’m running on 2gb of ram and a cpu at like 1.5ghz. My specs are:
i7-8700k at 4.7mhz max Amd Rx 6750xt 16gb ram at 3200mhz Linux is on an m.2
Any ideas? This is practically unusable for any normal operations, let alone any gaming.
In addition to the CPU throttling itself due to thermals like you said, you should also be aware that all Ubuntu’s are replacing more and more traditional packages with snaps for an increasing number of applications.
Step 1 (by the system) of opening a snap application for the first time (since boot) is to extract the compressed snap image, which makes startup time significantly longer (like several seconds for something you would expect to be instant). Once the application is started performance should be the same as if the application had been installed as a traditional .deb package.
You should also consider adding flatpak support and flathub. Applications installed as Flatpaks generally integrate better in the desktop than snaps, and flathub has a large and growing selection of apps. The flathub website has a few command lines you can copy-paste to enable flatpak and flathub support, then apps from Flathub will show up in the Discover app store.
Personally I use Kubuntu and use both Flatpak and snap apps, but generally prefer flatpaks when they’re available. And any software where I don’t care about having a recent version I install as a traditional package because it’s more lean
