Computer feels laggy running Linux but okay with Windows 10 don't know why?

- Processor: AMD A8-6600K APU with Radeon(tm) HD Graphics 3.90 GHz - Installed RAM: 8.00 GB (7.20 GB usable) - System type: 64-bit operating system, x64-based processor - Pen and touch: No pen or touch input is available for this display - HARD DISK DRIVE: TOSHIBA(every os uses the same hard disk with the same amount of partition) This is my computers specification. Now my question is when run Windows 10 on my computer it is literally faster(performance, dragging an application, startup of an application etc.) than running Linux (arch base{KDE PLASMA}, Debian base tried{KDE PLASMA}). I don't know why it happens, but it really annoys me because I know linux should run faster on my PC as it consumes less RAM and moreover the desktop is blurry too in Linux rather than Windows. Will ubuntu give me more better performance than arch or debian?
