Definitely, ram is like money... the more you have, the more you need!
I ran Lightroom and Photoshop on a 16 GB iMac, ran fine, but occasionally it would slow down, looking at memory use with Activity monitor there were times where swapping was happening, so my goal was with my current machine to eliminate disk swapping - 32 GB of ram almost eliminates all swapping for me... last check shows I have swapped 92 MB in the last week.... it used to be several GB per day...
The internal Fusion drive does work well for me, (2 TB spinning plus a 128 GB SSD) BUT, I think my next iMac will have an internal SSD.

First, you need to see if memory is the problem. Launch the Activity Monitor and check out the memory tab. If it's maxed out while using LR & PS, you need more RAM. Otherwise, it may be an issue elsewhere (not really sure if it's a fusion drive issue).
Have to agree with Steve - 40 gb should be lots of memory. When you look at Activity Monitor you should look at the bottom of page to see Memory Pressure. There you want to look at Swap Used. If you see anything other than zero there you are running out of memory and it is swapping to your HD (not SSD). That will slow you down greatly.
If you do see zero there then I doubt it is the fusion drive. Im assuming you have installed LR on the ssd and are storing the images on the hd part?

I wish you could install software on the SSD portion....the Fusion drive is managed by the OS, it determines what goes on the SSD portion based on usage...pretty much your OS and your most used apps/data fill up the SSD, so if you keep your image library on the internal Fusion disk, it can end up eating up your SSD portion instead of having your apps loading from the SSD.
You are spot on on the swapping issue though!
