Is it possible to make Ubuntu 18.04 boot faster (with dual-boot with Windows)?

  boot, linux, ubuntu-18.04, windows

I am new to Ubuntu Linux and just installed version 18.04 on my computer alongside Windows in dual-boot mode. However, after three weeks, Linux started to be very slow, and it will even crash a few times a day when it is not able to run my code efficiently enough.

CPU specs, gotten with lscpu are the following:

Things I tried so far are some of the solutions found on the following website: https://www.maketecheasier.com/linux-running-too-slow-heres-how-to-find-the-cause/. Such as: checking my CPU size (seems okay), examine CPU load with top (no process seems to be abusing my CPU usage) and check if my hard drive is overworking with iotop (it is not). Someone also suggested checking my bios version, which is the following:

N82 Ver. 01.45

I have no idea if this is the newest version, but I have googled a bit on updating my Bios version and with a dual-boot it seems like something that can go wrong easily. Since I do not have a lot of knowledge on this, I didn’t want to take the risk not knowing if this is even causing the problem.

Another thing I found on this forum (https://askubuntu.com/questions/1284302/is-it-possible-to-make-ubuntu-20-04-boot-faster) is examining the system with systemd-analyze blame:

           835ms dev-loop2.device

It seems like the upper lines are taken up a lot of time, so maybe this is a cause of the problem. The final thing that should be noted is that my Ubuntu running slow is mainly caused when I am using Visual Studio Code for too long – when my Ubuntu has just started, it runs fine, but after a while it gets slower and slower. I checked again with the top command the CPU usage when running a code in Visual Studio Code and it seems like maybe this causes a problem: command cc1plus runs at 99-100% of CPU.

I am sorry for not stating a clear question or problem cause, but I do not have any idea what might be the problem. If anything else is needed I’ll provide it.
