How to reduce the size of the space occupied by an array?

Question

C++ / C#

There is a ViewModelCollection, into which the logs arrive, and then displayed in the view.
All logs are needed, nothing can be deleted while the application is running. But there was a problem - after 20 minutes, there were already about a hundred thousand logs and RAM -700mb.
Whether it is possible to "compress" all this business somehow?

Throw off the logs first to disk, and then read and display in pieces.
In memory, keep only some adequate piece in order to have time to load the next pack while the user is scrolling.
