Batch SSH Commands for Speed | Generated by AI
Pushed. Here’s the summary:
Root cause: 9 separate SSH round-trips per remote machine. Each SSH handshake = TCP + key exchange + auth. DMIT alone was ~18s.
Fix: batch all commands into one shell script, pipe via stdin to ssh ... bash. One connection, one round-trip.
Results: local: 0.1s (unchanged) workstation: 0.9s (was ~5s) dmit: 2.5s (was ~18s) all three: 3.3s (was ~30s+)
Also fixed macOS fallbacks — cmd | awk returns 0 even when cmd fails, so || fallback never fired. Replaced with explicit if command -v checks.
