I am not sure if commit number is a problem because it looks only 300 commits are loaded.

This is a known problem. What happens here is that normally lazygit only loads the first 300 commits, that's why it's tolerably fast even in huge repositories; however, when you scroll all the way down to the last of those 300 commits (or press > to get there quickly), lazygit loads all commits, and this currently takes so much memory that it either gets unbearably slow, or even crashes.

And the same happens when you press / to search: this also triggers loading all commits, on the assumption that you may want to search them all.

There has been some work on improving the memory consumption, see #2533. I'm planning on picking up that work again relatively soon, but I can't promise anything.
