32 Jobs Sweet Spot | Generated by AI

Home 2026.06

Done. Here’s the benchmark:

Jobs    Time     Speedup
────    ────     ───────
 8      24.1s    1.0x (baseline)
 32      9.9s    2.4x  ← new default
 64      9.6s    2.5x  (diminishing returns)

32 is the sweet spot. 64 saves only 0.3s over 32 — not worth the extra connection pressure.

Changes made:

  1. ww/git/git_update.py — default jobs 8 → 32
  2. git config --global submodule.fetchJobs 4 — parallel submodule fetches
  3. git config --global http.postBuffer 524288000 — 500MB buffer for large repos

You can still override per-run: ww projects update -j 64 or ww projects update -j 16.

Also: that 1 failed repo — want me to check which one it is?
