Try the render presets if you haven't already. If you are using older settings they may be slower than necessary.

Try using Optix if you have a suitable GPU and haven't been already.

I did not really like the PostFX denoise when it was all or nothing, but it's great that you can tune how much denoising you want now. The PostFX bloom is really great when you are doing the sorts of things is makes sense for (e.g., lights or ambient materials in darker settings) and irrelevant otherwise, but it's worth rendering something appropriate so you can play with it.
