Studio using lots of RAM after quitting

Why is studio using lots of RAM after I quit? I have 16GB RAM, about to double that soon, but its crazy. Long minutes after I quit studio, there is a process taking up lots of RAM, for long after I quit. Slowing my whole system down until I ctrl+alt+del and end the process. What is it doing? I do not use DIM or connect, so what it could be doing after I save and quit is beyond me.

What is the name of the process ? is it the actual "Studio application" process or something else that does not exit ?
You say it is slowing down the computer so it is not just taking up ram, the task manager show CPU usage for it ? (I assume you are using Windows)
when you "quit" the application, Daz work until the temp is totaly empty!
sometime (depend of the scene) the time to end totaly the application is more than 2 minutes,,(check task manager)
more fun when you quit, the use of memory sometime goes up ,, (more than 15%)
Has never happend to me, it never takes more than a second or two for DS to close down, but maybe IRAY dependant, don't use it.
But might be a little like the early Microsoft Office installation in the 90th, sometimes when trying to uninstall it you got a message that you did not have enough free diskspace to uninstall MS Office ;)
in screen DS close fast,,
but in the background he continue to work for LONG TIME
Yes, the program UI closes, but the process is still staying open, using RAM and making my computer slow. My CPU usage isn't high or anything, and it's not using nearly all my RAM, but computer is running slow until I end the process with task manager. It's cleaning up temp when it's doing that? My computer is not a monster or anything, i5 7500 with 16GB RAM, but it's not a wimpy rig either.
When I say "close down" I do mean the process is gone and all memory released back to the OS, it never ever takes over 2 seconds after I close the application, so it does sound weird to me unless as I said it has something to do with IRAY as I don't use it.
It could be iray, that's what I use. It's really weird though, I am worried about temp getting bloated now, since I been having to end the process with task manager. I don't use connect or DIM or smart content either.
I get this all the time, particularly on larger scenes. See screenshot - using 9% of a monster CPU and 11GB of memory about 20 minutes after the relevant scene closed. I'm going to raise a support ticket beacuse it looks like some sort of glitch to me.
This happened on my old rig that only had 6gb of RAM. My scene would get written to my virtual memory after it exceeded my RAM capacity. It would take 5-15 minutes to clear.
On my new rig I watched RAM usage after I hit render and saw that for every gigabyte of RAM in a scene DAZ used another 2gb when it was sending the scene to the GPU. So if you have a 10gb scene you will need at least 32gb of RAM or it will start writing to your virtual memory. I think clearing VM is a much slower operation.
I have a GTX 1070 so 8gb of GPU RAM exceeded my 16gb of RAM. After I upgraded to 32gb of RAM I didn't have that slow purging of memory or DAZ performance issues.
Check it out yourself via "Resource Monitor, press Windows +R, type Resmon.exe".
After you quit the Daz Studio it continues to work in the background to free up all the memory/resources that were being used...this is normal. If you had a big scene, it will take longer, maybe a lot longer. On the other hand, if it is not freeing up the memory over time, maybe there is some glitch.
