SQL Developer amazingly slow

I'm not sure if I'm doing something wrong, but I simply cannot run any query without having to take a lot of time. I did this:

& got this:

I've no idea what's going on, or if it's on SQLDeveloper side. But this happens with every query I try to run.

Any ideas?

SQLDeveloper is great, but it has a habit of acquiring more and more memory until your PC starts paging and things grind to a halt. Then you kill it with task manager and things go back to normal again. I wish I had a solution to this.

Did you try something lighter? Like DBeaver e.g.
I installed DBeaver, but it can't download the Oracle drivers - not sure if it is our network or the repository. Unless someone can explain in simple terms how to obtain the correct drivers and how to install them it is no use.
