Can I suggest that you Restart the Mac…and then enter Roon…allow the Spinning wheel to finish…and then see what the Responsiveness is like after that?
Also, can you go to Settings —> Library —> Clean Up Library —> and allow it to go to the “Library Maintenance” screen that follows
Do NOT click on the “Clean Up Library” option…want to get more input from the Roon guys first
Can you then take a screenshot of that screen and post it here??..[Cmd+Shift+4 will allow you to draw a rectangle around that part of the screen and you will hear a Camera like click as it takes the screenshot]
@Ronnie, I’m afraid I have already cleaned up my library this afternoon, after the tests with USB ports, cables and SSD drive. Hope this is not a problem for the Roon guys.
Also, I’m blushing here, because the responsiveness seems to be back after restarting the Mac… sorry about that… 
@Ronnie ---- Thank you for all the feedback, tips, and insight here 
@koen ---- My apologies for the slow response here. I wanted to touch base with you as I have scheduled a meeting with my team for tomorrow morning to evaluate this behavior you have been experiencing to identify any variables that may be causing this to occur and thus, hopefully offer a resolve. I will be sure to follow back up with you immediately, once I have some feedback. I greatly appreciate your patience while I look into this for you.
Many thanks!

@Eric, thanks for your reply and looking forward to your feedback!
Hi Koen
Glad that Roon seems to be behaving again…while waiting for feddback from the Roon guys…if you do experience a lack of responsiveness here again…can you open the Activity Monitor on your Mac
Click on CPU…and Reverse Order it by Processes using the most CPU…then take a screenshot and post it here
Just want to see if there’s a non-Roon process running in the background that might be causing an issue
@Eric, a suggestion to bring to the meeting: when changing my trial to a Lifetime Membership, at my request, my Roon account was also transferred to a different e-mail account. Perhaps this has absolutely nothing to do with the issues I’m experiencing, but perhaps it explains everything (database gone corrupt, no idea, but for what it’s worth… 
).
Hey @Ronnie, thanks and will do! Luckily, at this moment no strange things happening in both Roon and the Activity Monitor (already firmly tied it to my dock over the past few days! 
).
Hi @koen —— Thank you for your patience. I had a chance to touch base with my team and one of our developers today to discuss these observations you have made while using the application.
We have thousands of users with similar setups functioning normally, so the observations you have made do seem to be unique and my team agrees that this may have to do with sheer size of your collection or perhaps the the device it is being stored on.
I understand from your last post that things seem to have stabilized, which I am pleased to hear. My developers have asked to keep us updated and should these issues crop back up, we would definitely like to grab some logs and take a closer look.
I can confirm that the sluggishness while performing searches in Roon is a known issue and has been addressed by our developers. We’ve done some performance work over the last month, and larger collections should benefit quite a bit from that work. Search performance and audio analysis have received a good deal of attention, so I expect the issues you’re describing to improve once that 1.3 is deployed.

Hi @Eric, thanks for your effort and feedback. Also, the offer to take a look at some logs if the problems return is appreciated.
For now, things indeed seem to have stabilized. Roon runs smoothly, no hanging or skipping. Average CPU is between 10 and 25 %. The tip from @Ronnie to use the Album view as a default screen and search via Focus from there (instead of using the magnifying glass) helps a lot. All in all quite a different experience using Roon now and a happy user again 
The magnifying glass still requires 110 % CPU and more, so the performance work is good news. Looking forward to 1.3 even more now! 
The only thing that still puzzles me a bit is your remark about my collection and/or the device. Is my 14k album collection (too) big for Roon? I thought I read on the forum that people with 50k collections have no performance problems at all. Are WD My Book 8TB HDD’s known to render problems? Would I gain speed by replacing its default power cable by e.g. an iFi iPower? Any more details on the analysis of your team and/or suggestions to improve upon are much appreciated!
Also, a final question: would things improve if I take the Mac Mini i7 upstairs, together with the WD HDD, install RoonServer on it, and take the older Mac Mini downstairs to run RoonBridge on it, connecting both Macs with an ethernet cable? And does this mean I have no GUI downstairs (RoonBridge) and upstairs (RoonServer), requiring the purchase of a device (iPad/iPhone) to use as a remote? Or is there a way to still have some GUI to control and edit my library with just RoonServer and RoonBridge?
Hi @koen ----- Thank you for the follow up 
In regard to your questions…
“The only thing that still puzzles me a bit is your remark about my collection and/or the device. Is my 14k album collection (too) big for Roon? I thought I read on the forum that people with 50k collections have no performance problems at all.”
Please allow me to offer some further insight here, and apologies for any confusion my comment about your collection size may have caused. As mentioned, with 1.3 quite a bit of work has been put into further enhancing the overall user experience, and one area that should see these benefits is our handling of larger collections.
As Brian has very eloquently pointed out in that thread:
“That said, there are definitely some areas where Roon could be optimized, and some specific performance oriented projects are planned. We are just wrapping up a round of optimization on RAAT–our next scheduled bit of performance work is focused on improving library related performance, with a focus on mac and linux, which should help here.”
"Would I gain speed by replacing its default power cable by e.g. an iFi iPower? "
Replacing the power cable for your storage device will not increase it’s speed or capability of handling media.
Would things improve if I take the Mac Mini i7 upstairs, together with the WD HDD, install RoonServer on it, and take the older Mac Mini downstairs to run RoonBridge on it, connecting both Macs with an ethernet cable? And does this mean I have no GUI downstairs (RoonBridge) and upstairs (RoonServer), requiring the purchase of a device (iPad/iPhone) to use as a remote? Or is there a way to still have some GUI to control and edit my library with just RoonServer and RoonBridge?
If you have the option of a stronger machine running your core it is never a bad idea 
I would honestly consider running Roon Server on that device and running Roon Remote on the older Mac.

Thanks for your detailed reply @Eric. I’ll digest this and will definitely take my current setup a level higher!

Hi @Eric, I’ve just switched both Mac Minis and am now running Roon Server on the i7 and Roon Bridge on the older one. For the time being, I control both machines via the GUI version of Roon (pending a new iPad/iPhone) and this works fine. I’ll order some ethernet cables to abandon wifi.
Great that Roon 1.3 will also enhance handling of larger collections, another reason to look forward to its release! Thanks for your advice and I’ll leave you to focus on 1.3!
