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 4.7ghz 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.

Update: So it seems like my CPU is being throttled to it’s min of 800mhz because the temp is just below 100c. Not sure why it’s so high because I never got that high even in intensive gaming on Windows

    I would start by checking for any sort of errors in your system logs, such as /var/log/syslog or using dmesg -w. In my experience, Linux is almost universally faster than Windows.

      Yeah, there’s probably something wrong. This is good advice. Maybe some tool can also do a performance benchmark to find the culprit. I’ve seen a lot of Linux computers. And except for some strange hardware, it’s supposed to be (at least) as fast as anything else.

          Yeah sure, keep working in your delusions.

          GNOME Shell is tightly integrated with Mutter, a compositing window manager and Wayland compositor. It is based upon Clutter to provide visual effects and hardware acceleration.[20] According to GNOME Shell maintainer[21] Owen Taylor, it is set up as a Mutter plugin largely written in JavaScript[22] and uses GUI widgets provided by GTK+ version 3.

          https://en.wikipedia.org/wiki/GNOME_Shell

          And yes, GNOME is slower than Windows, KDE and Xfce. Always has been, always will be. It might be polished but it is slow.

            where is written that gnome is a browser?, they only use javascript, like they could have used anything else, still don’t make it a browser, or like one

            and yes it’s lighter than windows, proved by ubuntu being recomended for lightweight OS(even when they use extensions and Snap), and where i said that it’s lighter than KDE and Xfce for you to bring it up lol

              By definition something that executes JS and parses CSS is a browser.

              and yes it’s lighter than windows, proved by ubuntu being recomended for lightweight OS

              Absolutely not. It gets recommended as a lightweight OS because 1) there are delusional people and 2) if you remove and stop everything on Windows 10 that you don’t it will be faster, way faster than anything running GNOME.

              The problem isn’t the OS per si, the problem is the UI. GNOME is SLOW as hell and even if the OS behind it is way more efficient than Windows it will lose against a debloated Windows 10 setup because Window’s UI is fully native and way faster.

                This is wrong. A browser parse a html document and construct a DOM, executing JavaScript and CSS are optional. GTK apps don’t have DOM, GTK has ability to parse UI styles from css instead of from XML so styling can be separated from UI definitions. Modern UI toolkits like QT (used extensively by KDE) also have CSS supports.

                I agree GNOME is resource heavy however that has nothing to do with Javascript being involved. The James Web Telescope uses Javascript for some of its core functionality (specifically managing its science modules), does that make it a web browser? I personally don’t like GNOME either, but most of it is written in C, it has its own GUI library which is written in C. The Javascript code likely just is used to simplify calling the underlying C functions and CSS is used for customizing the actual UI elements.

                  You know, it’s not that I don’t like it, but if it was faster things would be better. Even on a 10th-gen i7 with all the RAM launching an App on GNOME is always slower than KDE or Xfce. You feel a slight delay, maybe half a second or so.

                  To be honest their entire ecosystem is very used friendly and you’re kinda forced into GNOME as most GNOME apps will pull a ton of GNOME components with themselves even if you’re on KDE or others.

    Since you mentioned high cpu temps, do you have a water cooler? It’s possible that the pump is running at a reduced speed or not at all. If it was functioning fine on windows that leads me to believe that it’s not hardware related like some are suggesting.

      I do have a AIO radiator. The pump itself is plugged into CHA_FAN1 and shows about 1600RPM, but I don’t remember the normal speeds

            That would be where I’d look first. A lot of AIO manufacturers only write drivers for Windows. There’s an old Reddit thread that has a few things to try. If this is your first dip into Linux get used to googling things. A lot of things. Ubuntu or Kebuntu are great OS to start on because there is always a forum post or a Reddit thread that deals with exactly what you’re dealing with. Once you are more comfortable I’d move onto Linux Mint or straight Debian. All those nice things that make Ubuntu easy to learn will eventually also hold you back.

            If your AIO pump came with a hub you likely need to use it instead of plugging directly into the Mobo.

            As an example my corsair AIO came with a hub and i didnt want to use it. Finished my build and found out i absolutely had to use it in order for the device to work properly.

            Do you know what model AiO you have? Some models report pump speeds as higher since they have multiple magnets triggering the RPM sensor, so the 1600 might actually be 800 or even 400, which is way too low for the pump.

            I would try setting the pump (and AiO fan) to 100% speed in the Bios for testing. Some pumps work well with a fan curve, some don’t.

            Edit with more technical details: Normally each revolution should generate 2 Pulses on the rpm Feedback wire. But Pumps don’t always follow this spec so might over or underreport their actual rpm.

            Look up CoolerControl I use it for my Corsair AIO, and my CPU cooler runs entirely off a USB header. But CoolerControl also supports motherboard headers.

            You can use it to make custom fan curves and check pump/fan speeds.

          AIOs typically pretend to be a fan and you would only need to use that with a custom loop.

        I’ve had similar problems in the past with an AIO, the pump should always be at 100%, so I usually do this through BIOS. My old Mobo had a dedicated pump pin, but the new one doesn’t, so I put it on a fan one and configured it to 100% all times. If the pump is not at maximum it might not move enough water for the system to cool.

        The problem here might be a difference between how Windows and Linux handle fan control, CHA_FAN1 is a chassis fan, it might be that Kubuntu is not using the CPU temp for it, instead relying on another sensor.

        Although to be honest I don’t think this might be causing your issue. I’m leaning more to thinking this is related to either the snaps or some problem with the disk you have Linux on. My recommendation is to test a live iso for different distros, if the live iso for Kubuntu works better than on the disk it might imply some issue with the disk, if it’s also slow it might be a problem with Kubuntu, I would recommend then testing different distros with KDE Plasma, they would look and feel the same but might be faster if the problem is Ubuntu’s snaps. I personally don’t like it but I’ve heard people speak highly of Fedora and OpenSuse.

        I’ve had a few issues with fan control on AMD hardware. In your motherboards BIOS, try taking all fan control off auto, and set it for full load. In your OS, download Radeon-Control (AMD GPU Fan control) and set it for full load. See if your Temps stay high. I think Kubuntu comes with Fan-GUI (I think that’s what it’s called). Disable it.

      Any Ubuntu affiliated distro is required to use snaps, so Kubuntu will use them. Startup times are terrible, but running performance should be the same.

      Another simple distro to try would be either Mint or Pop-OS. Both are still Ubuntu based, but without snaps

      Mint’s interface (Cinnamon) is similar to Windows, Pop-OS uses a modified GNome

        Install “nvtop” to see all GPUs Performance graph. I do not remember if Intel was supported for Performance graph, but at least you can see a change for your AMD GPU.

      I don’t think it would be throttled to 800Mhz if this was the case, though. It definitely sounds like their cpu cooler isn’t working right. Maybe due to a kernel bug somehow, or maybe it just coincidentally died right when they moved to Linux.

    You didn’t mention what kind of cpu cooler (that I see). Have you checked there is fan spin for cpu fan? Possibly in windows you’ve got software controlling fan speed and that link is missing in Linux so it’s trying to just passively cool it? Even more complicated to diagnose if it’s an aio but could be similar with no pump running.

      KDE wouldn’t be slow on the kind of hardware he’s using. I’ve used it on far lower end hardware with no noticeable slowdowns.

      Yes, KDE requires hardware accelerated graphics and more memory to run smoothly, but anything built in the last 10y should have no issues meeting those requirements.
