Real-World Log Density Highlight (32.0 MiB Payload)
X-Lex™ Engine:89,909 B (~373× reduction vs uncompressed; ~3.1× smaller than zstd-3) — 166 ms encode (1-thread, indicative)
zstd (Level 3):281,939 B (~119× reduction) — 60 ms encode (1-thread, indicative)
xz (Level 6):227,156 B (~148× reduction) — 2,112 ms encode (1-thread, indicative)
Key takeaway: On real-world NDJSON observations (32 MiB), X-Lex™ delivers ~3.1× the compression density of zstd-3 (89,909 B vs 281,939 B) and ~2.5× the density of xz-6, while encoding much faster than xz-6 in this example. zstd-3 remains the fastest encoder here. Sizes are the hard claim; times are indicative — measure on your machine.
