Jnews. In the backend, everything is very slow.

I’ve installed jnews.
There are 17,000 records in the project.
When working as an administrator in the backend, everything is very slow.
Long waiting for a new record to open or for an existing one to be modified.
What possibilities do you recommend to increase the performance and speed of work?
What plugins can help you with this?
