I have two laptops:
Old HP Elitebook: 6th generation Intel CPU, 4 cores, 8 GB memory, 128 GB SSD, and Ubuntu 16.04;
New Dell XPS: 8th generation Intel CPU, 8 cores, 32 GB memory, 512 SSD, and Windows 10.
In both laptops, I installed LibreOffice 5 Writer.
On the HP laptop, Writer works quickly and smoothly.
On the Dell laptop, Writer is "sticky" - there is a noticeable delay after almost anything I click.
It is quite frustrating: I bought an expensive laptop that should be better in every hardware-related parameter, but got worse performance. How can this be?
Is it because Windows, in general, is slower than Ubuntu even on faster hardware?
Is it because Dell laptops, in general, are slower than HP laptops even with faster specs?
Is it because LibreOffice is optimized for Ubuntu, so it specifically is slower on Windows?
Finally, is there a way to make LibreOffice faster on Windows? Based on some Internet advice, I tried switching OpenGL on and off and did not notice much improvement.

1LibreOffice should not lag on most PC's, Windows or Linux. However, you can easily compare the performance: create a "live" Linux USB that includes LibreOffice, such as Ubuntu, and run it from the USB on the Dell without bothering to install Linux. Even though a USB flash drive is slower than HDD (much less SSD), once loaded, Writer should run full speed. My guess is that Windows OS is busy doing other tasks, such as performing updates. – DrMoishe Pippik – 2018-11-16T06:45:35.057
Do either of the laptops have dedicated graphics? What screen resolutions? Does the HP have an SSD while the Dell has an HDD? You are missing a lot of important system specifications that would establish why one system is "better" than the other. – Mokubai – 2018-11-16T08:12:32.583
Is it only Writer which is "sticky" or does that also apply to other programs? A new installation of Windows may be a bit slow while it indexes files for searching and updates. – Andrew Morton – 2018-11-17T16:38:32.280
There are too many variables for a definitive answer. You will need to assess this under controlled conditions. – fixer1234 – 2018-11-18T02:38:27.193
