Lossless JPEG XL encoding is already fast in software and scales very well with the number of cores. With a few cores, it can easily compress 100 megapixels per second or more. (The times you see in the comment with the DPReview samples are single-threaded and for a total of about 400 MP since each image is 101.8MP.)

HALIC does almost the same degree of compression tens of times faster. And interestingly, it consumes almost no memory at all. Unfortunately, this is the case.

HALIC being faster still doesn’t mean that lossless JXL is so slow as to warrant hardware acceleration.

Yes, I also think that HALIC should be destroyed ;)
