We're not Adobe here in this forum, we're just users like yourself.
If you'd like some advice or help, you'd need to state exactly what actions in Lightroom are slow. And also state your operating system, hardware configuration (including monitor size in pixels) and size of your images (in pixels or megapixels, not megabytes)
Just updated... and yes. Everything seems ridiculously slow. Not any particular action, but EVERYTHING.
Open a single image, waiting for it fully load full resolution at 1:1 view - awful. 60 seconds, when it's usually 5-10 for large 50MB raw files.
This is a dramatic change in performance that happened the instant the update finished installing.
