DRP size questions

I have a very large project that now has 77 timeline Masters. It's one of those client projects that just keeps growing over time.
It would be inefficient to have to break up this project into other smaller projects because I copy/paste from many different timelines etc.
That said, the project now takes 17 minutes to open up. It always opens successfully but it does take 17 minutes. However, once it is loaded, it only takes about 2 minutes to reopen the project even after a crash. Clearly, something is stored somewhere in a temporary RAM.
The project DRP file size is 335mb currently and growing.
I am curious to here about DRP sizes and project opening times for others out there who are working on large projects. Also, please include the number of working timelines too please.
Thanks,
Erik
