Building smart previews is much slower in Lightroom 6 than in Lightroom 5.
Creating a smart preview from a DNG (Fuji X-E1 raw file) takes about 12 seconds.

Enabling/disabling GPU accelaration does not really make a difference.
When monitoring the Lightroom process with Process Explorer the GPU usage is always 0.

Below is my system specification.

The CEF Helper process is started with the following parameters:

".\Adobe Lightroom CEF Helper.exe" --type=gpu-process --channel="2856.0.924264699\1390592871" --no-sandbox --lang=en-US --log-file="C:\Users\wmedetz\AppData\Local\Temp\\cef_debug.log" --log-severity=warning --disable-image-transport-surface --disable-d3d11 --supports-dual-gpus=false --gpu-driver-bug-workarounds=0,1,5,14,27 --gpu-vendor-id=0x8086 --gpu-device-id=0x1616 --gpu-driver-vendor="Intel Corporation" --gpu-driver-version= --lang=en-US --log-file="C:\Users\wmedetz\AppData\Local\Temp\\cef_debug.log" --log-severity=warning /prefetch:822062411

Any idea why this might be?

It also appears that you can no longer build large numbers of 1:1 previews at one time. When I request to build 1:1 previews for all my photos (>10K), it gets part of the way through, then dies with an out of memory error.
