Decompresses faster than LZ4
“Almost double the decompression speed, *and* a higher compression ratio than LZ4?”
Comment from 15 Jul 2026 in “Show HN: misa77 - a codec that decodes 2x faster than LZ4 (at better ratios)” “lz4's decompression speed was far slower than misa77 and zxc”
Comment from 15 Jul 2026 in “Show HN: misa77 - a codec that decodes 2x faster than LZ4 (at better ratios)” Nearly as fast as unsafe version
“is only ~5% slower than the current unsafe version”
Comment from 15 Jul 2026 in “Show HN: misa77 - a codec that decodes 2x faster than LZ4 (at better ratios)” “it's nearly as performant as the unsafe one”
Comment from 18 Jul 2026 in “Show HN: misa77 - a codec that decodes 2x faster than LZ4 (at better ratios)” Praised as promising, useful work
“Anyway good work, there is probably a need for that.”
Comment from 15 Jul 2026 in “Show HN: misa77 - a codec that decodes 2x faster than LZ4 (at better ratios)” “Nice results, I will keep a watch on this!”
Comment from 15 Jul 2026 in “Show HN: misa77 - a codec that decodes 2x faster than LZ4 (at better ratios)” “This looks awesome for boot firmware.”

“it's nearly as performant as the unsafe one”
“Paying a huge price during compression”
“All 3 things are show stoppers for any real use.”
“is only ~5% slower than the current unsafe version”
“Anyway good work, there is probably a need for that.”
“This looks awesome for boot firmware.”
“Overall quite good, but, depending on particular columns, most of the time slower”
“lz4's decompression speed was far slower than misa77 and zxc”
“It is slower than LZ4 on AArch64.”
“The gains are much more modest here due to asset data being mostly floats, but level 0 performs decently nevertheless.”
“Almost double the decompression speed, *and* a higher compression ratio than LZ4?”
“if you are not robust to corrupted/malicious data, it is really in a different class of algorithm”
“Nice results, I will keep a watch on this!”
