Specifically used enwik8.rar and enwik8.zip and ran precomp048dev.exe default and precomp048dev.exe with -intense to create the pcf files for compression. I did a few optimizations and got it down to ~3 seconds per 1kb in the last 24 hours. I ran command line precomp with default settings and -intense and other optimizations and was able to chop off 30% of the resulting pcf files ~3 seconds per 1kb chunk. I assume I can get sub 1 second performance single thread from MASM I used to program in MASM and I will give that a go to increase speed further. Should be able to get it down to 1kb chunk processing in ~2 seconds in a single threaded 2.2Ghz windows environment. I think that is part of the entire process of compression/decompression and yes lossless as well. Decompressing to the original file is not an issue. The only problem I have with the Hutter prize is having to release the code at this point. This is not my site so I am happy to just be here.
