Lightroom CC, both earlier version and 2015.1 version are extremely sluggish on my computer, Lightroom is ok usable not great with not exporting, but as soon as I export a batch of images it becomes completely useless. I have tried all the tricks in the book, disable GPU (I actually leave this disabled as LR performs a little better) reinstall, new user etc... I have plenty power, 14 core Xeon, 128GB RAM, TitanX, m.2 SSD and 4 stripe SSD work drive with up to 2.5GB/s read and write.

Previous versions of LR behaved much better.

Reporting in again, Building Standard previous makes LR unusable as well. As in when LR is doing 1 thing it seems it has to finish before one does anything else. Never seen this before with older versions of LR.

Please I work with LR ever single day and I am pulling my hair out.

Still extremely slow, when doing 1 action inside Lightroom it is almost impossible to use or do anything else at the same time inside Lightroom.

Have you tried this trick of setting LR's default priority to less then "normal" by changing the target of the shortcut to be this:

C:\Windows\System32\cmd.exe /c start "Adobe Lightroom" /belownormal "C:\Program Files\Adobe\Adobe Lightroom\lightroom.exe"

Counterintuitive as it may be, this can speed things up. The one thing you lose is being able to drag-and-drop onto Library to start an import, so I also have a shortcut that's the normal way for when I'm doing imports.

Tried this, still only exporting 4 images at a time in batch.

So, after quite a while... did you find a solution to this non-power-usage-issue?
I have a brand new powerful threadripper 1950X system (16cores) and have the same issue. Disabling half the cores does not help either...

Thank you very much for any helpful ideas!
