Serious How to fix lag spikes!

I did notice here and there on this forum that some have lag spike issues, and that others don't. I was part of those that do, and I found out a fix : Thread allocation.

No, that doesn't mean that you don't have enough RAM, that just means that it's used in a wrong way : Allocating 2GB should be enough to run a Wynncraft client, but the problem arrives where there's no RAM avaliable to Minecraft.

From my limited understanding of programming, Java has to salvage the RAM it has with something called a "Garbage Collector". I highly suspect that happens when a lag spike happens.. The way I did to fix this is... well... allocating more threads to Java using something in the MC launcher called "JVM Arguments".
more specifically.

I used =3, because I have 6 cores and run a lot of apps in the background too, but 2/3 to 3/4 of your CPU's cores should be enough. I need others to try this out and experiment with that JVM argument, so I can see if it's truly a CPU usage problem rather than a spec issue.

 

Uhhh too complicated for me

 

Trying this, I've been experiencing lag spikes and it debilitates me a lot, so I allocated 2/4 of my cores and not 3/4 as a start, will report performance

 

update: after an entire day with those settings, I went from having huge lag spikes every single moment to not having a single one, this definitely works (at least for me), and I do not have a strong pc at all!
I wish this post was more viral this'd help the community greatly

 

How to change this then?
