Bsp geometry cause huge slow down
Why developing I notice when I use alot of bsp brushes it causes a very huge slow down when trying to arrange them.

I'm writing this answer with the assumption that you have a large scene filled with many BSPs, thus causing slowdown.
BSPs are relatively inefficient and should not be used for creating detailed geometry (in my opinion) in most cases. They are often typically used for white boxing a level, or for simple wall and floor planes.
You can however convert them into static meshes, which should be done once you have finished arranging your BSPs, as you will not be able to revert them back from meshes to BSP. I found a tutorial here: https://www.youtube.com/watch?
If you don't like the idea of doing this, then I suggest that you either look into using 3D modeling software for your geometry (Blender is free) or I do have an alternative, if somewhat more complicated/advanced idea, which is to use level streaming to separate the BSPs into separate levels, which can be loaded and unloaded as your needs require.
