Minecraft Java

So, i experience like these lag spikes kinda that lag the screen and drop the fps in this version of the game and it’s my favorite version I just love Java over bedrock but this problem keeps occurring and I don’t know how to fix it I set my fps on 60 to get like a constant fps on it and it drops I put it on max to see what I would get to and it gets to around 110 then when I start running it has lag Spikes and goes back up and it does this repeatedly if anyone knows a fix for this I would really appreciate it I am using optifine it has helped a bit and it was doing the same without optifine also I have turned the settings down
