Replaces benchmark figures taken on a development build with measurements of the released v1.0.2 binary (gleipnir.exe, SHA-256 013522ab…6dc7). This gets the repository ready for a Mahoney benchmark submission.

Silesia. Per-file, -9 -t1, each archive round-trip verified by SHA-256:

  • 35,583,396. The development-build figure it replaces was 35,773,957.
  • That would place 49th of 320, ahead of paq8pxd_v4 -5 by 2,906 bytes.
  • The README per-file table and the paq8px sizes now use the release figures.
  • The 35,582,296 whole-directory figure in the headline table stays, now labelled as coming from the pre-release timing session.

enwik9.

  • v1.0.2 reproduces 157,073,381 byte for byte, with the stored name enwik9.
  • Decompression peak is now measured at 3,836 MB; before, it was only stated without a measurement.
  • The LTCB board now has 226 entries, so the placements move to 35th (one segment) and 47th (default -s64) of 227.

Also: the line count is now 4,701, up from 4,543.

Test machine: Ryzen 5 4500, 16 GB DDR4, Windows 11. Both board pages were re-fetched and parsed on 2026-09-23.

The per-file Silesia figures came from a development build (genf1.exe).
Measured on the released v1.0.2 binary, each file compressed on its own
and round-trip verified, the total is 35,583,396 -- 190,561 bytes smaller
than the 35,773,957 previously quoted, and 49th of 320 on the board.

enwik9 reproduces 157,073,381 byte for byte on v1.0.2, and decompression
peak is now measured (3,836 MB) rather than asserted. The LTCB board has
grown to 226 entries, so the placements move to 35th and 47th of 227.
