DPP4 *is* much slower than most other programs (including DPP3) regardless of GPU (more on that in a bit), but you won't feel it much unless you're at higher-than-FHD and/or on a slower-than-top-class CPU. That's because DPP aims for the best quality possible, and it's often possible to get better results than even Adobe RAW/Lightroom if you know how to use it, unless you need "local contrast" and/or "dehaze".
That being said, there are 3
features cases that worsen noticeably (and irritatingly) the already slow workflow:
1. working on 3k or higher resolutions;
2. enabling "Digital Lens Optimizer" (DLO);
3. noise correction.
If you use 2 or more of those, sit down and cry rivers. Also, custom tone curve adjustments and color correction, as well as Auto Lighting Optimizer (ALO) may add a bit of extra drag (and, naturally, the more you add, the worse), though these are much less impactful than the aforementioned.
What I do to counter this issue is:
1. do main edits (except sharpness) on a FHD display (if you're on 4k without dual-display, either work with DPP as a quarter-screen window or manually set display resolution);
1.1. if I need to fiddle with Noise Reduction, do it after the main adjustments, and if I really need speed, disable NR altogether when first editing (remember to write down NR settings beforehand) at this phase;
2. once I'm satisfied with everything, and only then, I turn on DLO and fine-tune the other adjustments (including NR), except sharpness;
3. only then I switch back to a higher resolution (i.e. maximizing on the 4k display) for the final kicks. Expect up to 30s between updates on slower CPUs (i5-750, i5-2500, i7-4500u) and 5-15s on faster CPUs (i7-7700HQ) patched against Spectre/Meltdown;
4. only then I adjust sharpness.
The drag is irrestrictive of GPUs, because they're only used for certain preview operations (i.e. when first opening files) that Canon doesn't reveal (if any). Most of the work is still done by the CPU. It doesn't matter which GPU you own (ATI 5770, GTX 960, GTX 1070), the difference is minimal and if anything you'll only see a small spike in GPU activity when initially opening files (and maybe in some other operations I don't remember). Not sure if it's used at all when converting to JPEG.
Actually DPP4.8 is *much* faster than the initial 4.0 releases. I hope DPP5 will improve on this if and when it's released.
Hope this helps.

Thank you for your comment. It is also my experience, but some advices I'll implement myself in future. It is a pitty that Canon do not provide such explanations. Instead they sugest to use GPU with CUDA (btw - "cuda" in Polish means "miracles" ).
Waiting for version 5.

My experience is that the camera (sensor?) type has a significant impact.
On my system a 6D file loads within 2-3s but a M100 file takes 10-20s or sometimes more (loading from SSD, 16GB RAM, i5-4570).
I assume different calculations are applied to files from different sensor types.

Well, this is kind of new. The previous topic concerned DPP version 4.8.X; this post concerns DPP version 184.108.40.206. I've used previous version of DPP 4.X which I liked. However, with this version I have the constant constant problem encountering the "Blue Circle of Death." Makes DPP virtually useless (to me). Has anyone else encountered this? If you have, how did you resolve the problem? All the other free Canon software work well
