Response Bundling

[Mygod]

This is a quirk of dnstt: dnstt fills each DNS response with as many downstream packets as fit, stashing overflow, and waits up to maxResponseDelay for data. /dnstt/dnstt-server/main.go:81 /dnstt/dnstt-server/main.go:700

• Benefit: (possibly) improves downstream goodput and reduces response count by amortizing TXT and header overhead. /dnstt/dnstt-server/main.go:734
• Benefit: fewer responses can reduce resolver rate-limit pressure and server CPU per byte.
• Risk: adds latency and jitter (up to the delay timer) and can hurt interactive traffic and mislead congestion control algorithm. /dnstt/dnstt-server/main.go:81
• Risk: larger responses are more likely to hit payload limits, causing truncation or wasted data. /dnstt/dnstt-server/main.go:805
