Z-9 raw import from CF cards very slow

So continuing the saga of importing from a cfExpress type b Card raw files from my z9. It takes about 9 hours to import roughly 4k files. I am using a reader and very fast cards for read and write speeds. Some of the events I shoot leave me with more than 10k images to import so just moving into a folder on my harddrive and then imporing is not practical as I end of with files with the same name spread over multiple cards...LR renames the file when writing to prevent this from overwriting existing images.  This slowness has persisted for several years now as I h ave been reading about this issue for quite a while. Adobe you can do better..please fix this.
