LR 7 Classic significantly slower

You're among friends now. We're all with you. 

The hard part here is that the 50gb catalog only represents 31,000 photos. My scenario is not an outlier and should have easily been covered. It’s real difficult to accept valid testing procedures were in place given this simple example. Continuing issues like these in a product now in release 7 are what gives Adobe a black eye and when the attempt to justify it by indicating there is no way to test ‘all’ combinations is used, it further points to their inability to objectively evaluate their internal procedures. Unfortunately nothing new here, and the ‘wait’ begins again. 

it's difficult to accept that ANY testing procedures were in place. Hell, I'm here because this is where ADOBE themselves sent me when I messaged them asking what they were doing about Lightroom's issues. 

It's like "Hey, I need help with your product.", adobe "Here, go to this place where everyone hates us."

I didn't change my workflow after updating to LR Classic. But after I had updated I found no situation where the App showed any progress – on the contrary: nearly everywhere I find backsteps, esp. in develop module and when syncing a folder. I am really upset. They didn't do anything for the now called Classic, the used the money we pay only for development of this useless playground called Lightroom CC now... This is not acceptable.

I am convinced the developers realised the update wasn't ready but with an announcement required at their conference they were forced to release. Now management appear to be refusing to acknowledge there is a problem and we, the mugs who have paid up for the next 12 months, are left with an unusable product.  I did receive a message from one of the techs assuring me they were looking into the performance issues but I hold out little hope in the short to medium term.  When I find time I am testing a number of alternative products.  I get many requests from new photographer on how to improve and, of course, one of the things I encourage them to do is to shoot raw and get a raw processor.  In the past my recommendation has been the standalone, or subscription model, lightroom.  Now that the standalone product is gone, and the subscription model is poor, I can no longer make this recommendation.  

Right now I have started looking at ACDSee and that maybe the product I recommend in the future.

Unfortunately with so many of us locked into a subscription for many months it will take a long time for Adobe to start noticing any revenue declines as photographers start ending their subscriptions, or there may be no decline as many of us want to continue to use Photoshop.  Here's hoping Adobe management start encouraging beta testers or do more thorough internal testing of their products before releasing under-prepared products to market.

Same here - have to ReStart Lighroom CCC  every 15 Pics in develop Module, or wait 20 seconds until i ́m available to do any modifications. During the waiting time there is no ssd write or CPU action visible.
 I ́m a wedding photographer and get more than 3000 Pics every weekend...the library modul is getting faster as in CC but the Develop Module is a nightmare !!!!

No resolutions here ?
