Welcome to the forum Dave.
Current version is 18.104.22.168 (for Windows).
I have not personally experienced the slowness, but based on what others have reported, it seems to be related to a file indexing process.

Using a solid state drive, I don't recall any issues with file loading speed but some camera files are slower to process. My 1DX III images are noticeably slower than those from the 1DX II, 1DX, and 5DS R bodies.
DLO (lens optimization) and noise reduction are the two largest speed killers, I leave those turned off in body and apply as needed late in the RAW processing workflow. The stamp tool is also fairly slow with the newer bodies. And slow is relative, I am using a HP workstation with twin Intel Xeon CPUs with a lot of RAM and solid state drives, most manipulations of files prior to the 1DX III take a few seconds at most while 1DX III files can take 15 seconds to complete a combination of NR and DLO.

I give each new version a try to see if Canon has eliminated the almost constant busy cursors.
Then I go back to my other RAW processing progs.
They would be better off making a deal with DXO to supply a stripped down version of Photolab specifically for CANON cameras.
Photolab processes CR2 and CR3 files very quickly.
