Why does LR slow down the more edits I make? Even if I restart it, still slow???

Probably because your video card takes time to render the edits you make. The editing you do is written to a very small file called a sidecar file, or to the catalog, depending on how you've set up LR. This file or catalog takes nothing for the computer to read or write to, but rendering the video on your screen is very intense.

I think the problem might be the JPEG preview setting.

I have mine set to Medium and don't have issues with it.

Another factor could be from activating "lens correction." Activating this function takes a lot of memory which frequently makes subsequent image adjustments slow and jerky. This lens correction step should take place toward the end of image adjustments.

I'll try that thx. I usually do that in the beginning. Are you talking about all the lens correction adjustments?

In addition to the suggestions already made, you might consider increasing the available cache size. It should be larger than the size of one of your raw files. Otherwise LR will have to hit the disk for each picture instead of working from RAM.

I also question the need to imbed the original RAW file within the DNG upon import. You will still have the RAW file, even if you don't imbed it.

Hope all the suggestions help. Slow is very frustrating.

Yes.

Is this a 32 or 64 bit system? What OS is being used? What CPU?
How much RAM do you have in this system? Also...do you have a dedicated video card in this system? How much RAM is resident on it?
Lightroom is typically a RAM dedicated program. If your system has only INTEL Integrated Video, then lots of your RAM (up to 3 gig) is stolen for video processing. This is one reason everyone recommends installing as much RAM in your system as your BIOS and OS will recognize. If you had a real dedicated video card with 1 or 2 gig of video RAM, the system RAM can be utilized by the program being run and this speeds up PP work rather than using HDD swap files for temp storage while processing your requests. Lightroom will also utilized up to 4 cores in your CPU when doing processing so some duel core systems might have "program halts" or use "temp files" on your HDD which will definitely slow things down.
Another suggestion is to run your OS and Lightroom on a 128 or 256 gig SSD which is vastly faster than HDDs but store your libraries on the HDD. Import them to the SSD when worked on.

My guess would be the equipment you are using, not enough speed, memory, etc. Go to the Adobe website and they post what they believe the minimum requirements are for effective use.
