here is a gif showing it starting and stopping with f3 on in the game to show what my pc/game is doing
when playing

Note: my programing knowledge is copy and past programing. I am a regular game player who really, really want's to play this pack. I just recently got a pc that can run this pack and i am still having issues running it.

Thank you for your time and consideration.

That lag spike is caused by java's garbage collection function. If you look at the memory allocation/usage in the upper righthand corner, you'll see it 'lag' when it hits 100%, then after the spike it will be lower again. By the looks of things, you have about 3GB set up for the pack, correct?

thank you for your help. I learned via your implication that their is a setting some where so I have been digging around in the settings pulling my hair out looking for answers. I found nothing in Minecraft but, I did find it in twitch.

I had no clue that it had an option in the settings for memory allocation.(I don't stream, only mod)

If any one runs in to the same issue I did go to settings select Minecraft scroll down to java settings and adjust from their.

unintentionally maybe... I just down loaded it and ran it as it was, so if that was the default setting how would I change it to run with more? I did try to allocate it by clicking on the button under better fps but nothing seamed to change.
