Is my project to Large?

So I have created a statistics project. At this time the largest issue I am finding is that I have atleast 40,000 events if not much more. The project is about 11MB in size when saved it has slowed down but now it crashes everytime I start to do anything even crashes when I save. Have I hit the limit of the program or is it my computer.

I am using an HP envy laptop with 16 gb ram and an i7 processor.

I am using the 121r but have always had issues of it slowing down the larger my project gets. I have just increased it greatly and I am hoping that is not the issue.

Anyone have any Ideas?

That sounds like an absurd number of events. What could you possibly need them for?

If you're doing something like copying and pasting whole lists of events and changing a number in each one, you can usually replace that with a better designed method, e.g. a loop or function.
