Lightroom export is VERY Slow

[edshanahan1@aol.com]

I can only export 10-12 images from LrC (11.4.1) to JPEG files/minute.  This is an issue when trying to deliver 1500 images to a client soon after an event completes.  It takes me over 2 hours to export these images. My catalog and images are stored on an internal 2T SSD drive, and I export JPEGS to this same SSD drive.  My export speed is 10-12 images/minute; my collecgues who also shoot these same events are averaging 3X this speed.  Interested in your thoughts as to how I might accelerate my exports. Tx.   

My 2019 MPB w 2.4Ghz, 8-Core Intel i9 processor should have more than enough resources to run this export VERY fast.  BlackMagic Design shows read and write speeds in excess of 2600 MB/s.   During export: CPU runs at 60%, 25G of 64G memory is being used, with 16G additional as cache; 

I have run many different tests, none of which have helped performance.  Tests include: 1) exporting old NEF files to see if my Canon cRaw fles are the issue.  They are not.  2) running export with my computer in Safe mode.  No speed improvement.  3) Playing with graphics card settings.  No improvement. 

I do not know what else to do other than to purge LrC and reinstall it from scratch.  I would really prefer not to do this.  Appreciate any help!

It is a graphic Watermark, the logo of the event. Just an idea how slow it is, it took 30 secondes to export 250 pictures without it, and now after 10 minutes it still work. That's horrible...

Wouldn`t it be easier to export the photos from LR without the watermark, and then bath process them trought PS to add the watermark? I know that two step process, but it could be faster.

That's ehat we did, on 35000 pictures. It was painfull...

You could export from LR without the watermark, then create a batch process in Photoshop to add the watermark

Love the program.  But Lightroom export is just simply slow. Period.

I have the same problem with Windows and AMD CPU. Previously all was working fine. Now when exporting images only one CPU Thread is used (enabling or disabling GPU does nothing) Export is really, really slow

Lightroom Export to JPG is much slower if you check "Limit File Size."  Uncheck that box then choose a Quality setting and the photos will export at least twice as fast.  Quality=80 produces images around 2.7MB, Quality=90 is around 4 MB.
