Lightroom Desktop: Export causes huge RAM usage

I recently got so fed up with Lightroom that I did a full Windows reinstall (so you can't blame that, which is your usual answer when all else fails). Exports have always been a nightmare for me. Sometimes I can get a few export, but anymore that 30 or 40 at a time and everything goes to hell. After the reinstall of windows and reinstall of Lightroom (the online version, not classic or whatever you call it) exports seemed to work fine again. I added a few albums over the last few days, 100-200 pictures a piece on average, and noticed that the exports began to slow down quite a bit. Today I tried to export about 140 pictures and everything went to hell, very slow and only made it to about 50 pictures. Checked task manager and the lightroom sync utility was using every available MB of memory. I have a Threadripper 2990WX, 32GB of system ram, Vega 56 graphics...seems like exports shouldn't be an issue. I'm so tired of this crap. You charge me every month and the software doesn't get any better. I get a new slider that does something stupid every 12 months. Whoop-di-do. I want to export more than 10 photos at a time...

 

I've tried rebooting. I've tried closing everything else. And again, I just did a full reinstall 4 days ago. There's not much else running on the system to begin with. The second I start an export RAM usage increases drastically until it reaches 99% and the system just slows to a crawl. At best I can get through about 20 pictures before that happens.

A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the preferences.

Reset Procedure:

1. Close Lightroom.

2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.

3. Overwrite the Preferences when prompted by the dialog.

4. Close Lightroom.

5. Restart Lightroom.

Does the behavior (Ram Usage) continue after resetting the preferences?

Nope, got through 79 pictures. Once I start the export nothing happens for a minute or so...then the first few pictures take another minute to export. RAM and CPU usage go up to 99-100% almost immediately during this time. Then the next 50-60 pictures export relatively quickly, like what I would normally expect. Then everything stops. Task manager still shows 99% CPU/RAM usage, but Lightroom is no longer showing that it is using those resources, but the export stops and the system totally bogs down. The system actually crashed while I was writing this the first time. Again, I just did a full reinstall a few days ago, everything seems stable (some Steam games, long benchmark runs) aside from trying to export photos. 

Just saw an update to Lightroom 4.0...maybe that'll fix it....

So it did complete the export now. I will say, the pattern still exists though, I'm not sure if that's expected. I begin the export and it sits for about 3 minutes on photo 1, memory usage goes to 99% at this time. The next 4 photos take about 2 minutes to export and then it goes it spurts, 20 or so pictures at a time. Where before memory usage would drop and then the system would hang, it continued after a pause with memory usage going back to 99%. 137 photos (24MP sony raw photos to 90% full size jpgs) took over 10 minutes, again, I'm not sure if that's normal or not.

3 Minutes a photo is abnormal in most cases. I would expect 10 seconds per photo or less.

2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.

I spoke to @Ankur on the Dev Team and he tells me we have some changes coming in the next release that should help.

Thanks for the update and suggestion. Unfortunately, the pattern still persists. I tried different photos and exported out to a different drive, but still just as described above, even after clearing the preferences again. 

I appreciate the help and am glad I'm being heard at least, but it's still very frustrating having this issue. Hopefully, the next release can remedy this.
