Lightroom 6 slow speed tested compared to 5.7 + GPU not used?

I've purchased Lightroom 6 last week, mainly because of the promised speed, but so far I have not been impressed - it feels generally sluggish to LR5.7. I did some igging on the internet and it seems my GPU (HD4600) is also not used (system info says "GPUdevice unavailable"), even though OpenGL is passed and I've installed the latest drivers. But even with GPU acceleration off, I think it's fair to expect at least a similar speed to LR5.7 - but unfortunately that's not the case.

I decided to do a little (admittedly kind of unscientific) test between LR6 and LR5.7. For these tests I've imported and exported 10 Nikon D800 NEF files in both programs with 1/1 previews and no presets applied. I made sure the files were not in the catalogue from a previous import and that import and export settings (JPG) were the same for both programs. Here we go:

LR6 import - 90sec
LR5.7 import - 45sec

LR6 export - 73sec
LR5.7 export - 39sec


So lightroom 6 seems about 50% slower than 5.7. (GPU acceleration on or off made no difference)

For someone who shoots a lot of weddings and has to do the above operations several times a week with hundreds of photo's, that speed decrease is a real problem - and I'm not even mentioning the general sluggishness when editing / swapping modules.

My system specs: i5-4670K, 8GB ram, HD4600 graphics, Win7 64 bit with latest drivers installed, catalogue on SSD. My website: 20Watt Fotografie

Sounds about right. I've switched back to LR 5.7 for the meantime. LR CC was taking ages to import and export a little over 300 5D3 files from a shoot yesterday afternoon. I switched back to 5.7 and things were completed in a small fraction of the time. My GPU is listed as compatible on Adobe's site. It has the latest drivers.

Absolutely everything in LR CC is slower. Edit in PS, any develop, 1:1 preview generation, importing, exporting... module switching...

My machine is running i7 clocked at 3.4 gig and 32 gig of RAM, catalogue on SSD.

So many Adobe problems lately...

Switching from photo to photo in the Develop module is also agonizingly slow. I click the right arrow to move on to the next photo and then sit back and crack a beer. It is a real detriment to how I use and enjoy the program. I have a 2011 Macbook Pro with an upgraded SSD hard drive and most things work as fast as can be humanly expected. Only LR6 is slow enough to annoy me.

Still no sign of improvement. I would NOT recommend people upgrade as I did. If you have, back out of it.

I agree. Not worth the slowness.

I'm so super frustrated. I thought I'd upgrade my mac but everything I've read said that it doesn't fix the problem. Please fix Lightroom so that it works as fast as it should. I'm ready to pull my hair out.
