Reduce SSH poll interval to 500ms with immediate probe#63
Merged
Conversation
Change sshWaitPollInterval from 2s to 200ms and probe immediately on entry before starting the ticker. This avoids wasting up to one full poll interval when SSH becomes ready between ticks. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
sshWaitPollIntervalfrom 2s to 500msWaitForReady()before starting the ticker, avoiding wasting up to one full poll interval when SSH is already readyProblem
The SSH readiness check polled every 2 seconds with no initial probe. When the guest boots in ~1s, the first probe doesn't fire until t+2s, wasting ~1s. With the 2s interval, worst-case waste is ~2s per boot.
