Nucrunch 0.1
Continuing from the benchmarks WVL posted in Doynamite 1.x:
I dusted off my unfinished nucrunch in December to pack just enough of the second page of Reutastic to give me some workspace for some precalculations. Pity I didn't schedule enough time to pack the entire demo, else it would have been ~90 blocks instead of 190, but I digress. I've spent bits of the past month cleaning up the code, optimizing the packer (mostly by porting it from python to rust :P), and adding reverse direction support.
It's still no more than a component, with an commandline packer and asm decrunch subroutine, but no tools yet for generating an executable from a single commandline. It does at least now support multiple input segments that are unpacked to their destination addresses, and it's also now useable enough to for me to do some benchmarking.
In short, doynamite's ratio looks pretty unbeatable for anything lz based; my ratio's almost identical despite a somewhat different encoding.
Where I can win though is speed at that ratio; nucrunch is usually ten to twenty percent faster. The one exception in the test corpus is 6.bin, where it's 20% slower; not sure why yet.
I've added the times for pucrunch -ffast below for to complete the comparison. Last two columns are nucrunch, and nucrunch -r (the latter decodes in reverse; should be a more useful component for single filers)
If anyone wants to have a play at this stage, poke me and I'll upload some source. Failing that I'll hold off until I at least have something that can make onefilers without any faffing about with relocating the last couple of pages by hand.

also with direct loading into registers and presorting to maximize register reuse upon same values, we get below 6 cycles ;-) For further brainfuck we can combine registers with SAX, SHA, ... on some stores :-D |

Quoting Bitbreakeralso with direct loading into registers and presorting to maximize register reuse upon same values, we get below 6 cycles ;-)
Exactly what's required for half-cell Koalas, or there wouldn't be enough CPU time to update 37 bytes of d800 values every four lines :)
But yeah, I was assuming the .bin was already in place, so this is the excess cycles over time taken to transfer from external storage, be it 1541 or something more exotic

Quoting MagerValpAdded timed benchmarks for LZMV, both the original 256 byte sliding window and the 4k version I used in U4. Note that neither is optimized for speed right now, but size and convenience.
Thank you! Looking very similar to TinyCrunch there, maybe I should be dusting that off too

Added results of exomizer mem. Butt slow. I also added average compression and total time to depack all 9.

Now just give us the Pareto Optimal set too and then we've settled this properly. ;) |

It would be invalid to treat Pareto efficiency as equivalent to social optimality. |
