Something to check when using DPP with Windows 11 is to check your power plan settings because the default Windows power plan may be greatly reducing performance with some programs like DPP.
Prior to fall football season, I wanted to speed things up with a faster workstation than the HP Z840 I have used for several years and in July I ordered a HP Z8 G5 with twin 28 core Intel Xeon CPUs and 128 GB of memory per CPU. My first experience with using DPP was less than impressive, marginally faster than my prior twin CPU Z series workstation but not as fast as desired.
I checked the power plan that Windows sets up during install and it was set to "balanced"; changing that to the included "HP Z ultimate performance" reduced conversion time for CR3 RAW to JPG from around 7 seconds per file to just over 3 seconds per file which is a significant difference when batch processing a few hundred images from a game. DPP still isn't really utilizing the system well with peak CPU loading showing 5% and although it has a pair of Nvidia workstation GPU cards DPP isn't utilizing the GPU units at all where GPU loading stays below 1% regardless of what DPP is doing and that 1% is being used by other applications.
If there isn't a custom power plan for your PC, then try Microsoft's generic ultimate performance plan and see if that speeds up DPP. Going to a higher performance plan MAY increase fan noise for some computers. My HP Z8 G5 uses vapor cooling for the CPUs and has multiple fans for the various components and has never come off idle fan speed during DPP usage with CPU temperature rising only 1 to 2C above idle but with less cooling and processing capability, you may see different results. In any case it is worth trying to speed things up.
So overall, I am happy with the upgrade and both editing and raw conversion are much faster with the new workstation but DPP still needs work (and not just more of the ongoing tweaks). It also still has the memory leak issue that has plagued almost every version of DPP since I started using it 20 years ago. After 3 hours of editing this morning, DPP had grown to 11 GB in memory size which is still a tiny fraction of the 256 GB of available memory but even though plenty of resources are available editing begins to slow a bit. The only fix is to exit and relaunch DPP and then it is good for a couple more hours.
