Slow in Denoise and Album operations

[PhotosByFonzie]

PLEASE. HELP. Photography is my primary profession and this god awful performance is crippling my work flow. Its gotten increasingly slow with each new update. 

Everything else runs blisteringly fast. User benchmark shows me in the top 10% in performance.

Im running:

ASUS X570 TUF GAMING w/Wifi
AMD Ryzen 9 5900X 12-Core 3.7 GHz Processor
GeForce RTX 3070 TI 8GB (PCIe 4.0) - latest studio drivers
128 GB DDR4 3600MHz 18-22-22-42 RAM (32GB x 4)
4TB NVMe WD Black SN850X (7300 MB/s read/6600 MB/s write) PCIe 4.0 installed in the M.2_1 slot (closest to processor)
Windows 10 Pro

- Moving photos or removing/deleting albums takes obscenely long and culling is obscenely laggy. (Even in develop tab)
- denoise takes nearly twice as long vs initial release
- significant stuttering and lag after editing albums, have restart app or the computer

Yes, I have…
- latest updates.
- tried turning off sync
- disabled GPU
- tried experimenting w/preview quality up and down
- optimized catalog
- increasing cache

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut out as that is just so much dead space to us non-Techs and it takes up vast amounts of scroll space making the reply less readable and less likely that others will bother with your post.

• So, is this your only hard drive?
• And your catalog is on it?
• And your Camera RAW CACHE is on it?
• 4 TB should be plenty, but if your catalog is on it, then how much free space exists on it? (preferably % free looking for at least 20% free)

Can you post in a reply a screenshot of Lrc /Preferences/Performance/

denoise takes nearly twice as long vs initial release

Are you comparing AI Denoise to AI Denoise, or AI Denoise to manual Denoise?

Check your Windows updates, did you install KB5043145? Hopefully not.

Also, did you update to Windows v24H2 (build 26100).

If either is the case, check for updates, looks like MS has published fixes.

I have same issues since May ... this weekend, I tried to kill some process to check behavior. And surprise, when I kill "Adobe Content Synchronize" processus several times, LRC become faster. Could you try by your side and tell me ? Because even is synchro is off, this processus seems to be active ...
