Performance Tuning

Dispatcher Performance Tuning (AMS)

Improve cache efficiency, latency, and throughput for AMS deployments that use the Adobe Dispatcher Apache HTTP Server module and related HTTPD configuration.

Variant Scope

• This skill is AMS-only.
• Scope is fixed by this skill directory; do not ask the user to choose deployment variant.

MCP Tool Contract

Use only these Dispatcher MCP tools:

• validate
• lint
• sdk
• trace_request
• inspect_cache
• monitor_metrics
• tail_logs

Workflow

1. Capture baseline metrics and cache evidence.
2. Apply AMS 6.5 guardrails (tier boundaries, variable-driven config, flush ACL safety) to candidate optimizations.
3. Prioritize low-risk/high-impact changes.
4. Apply minimal edits.
5. Verify with validate, lint, and sdk.
6. Compare before/after runtime evidence.

Verification Scope Selection

Use shared references to select optimization evidence depth:

• mode-specific-verification-matrix.md
• test-case-catalog.md

Output Contract

Always return:

• baseline metrics snapshot
• prioritized optimization list with impact/risk
• changed files and intent
• executed checks + before/after evidence
• selected test IDs and outcomes
• rollback plan and open risks

Guardrails

• Do not claim improvement without measurable comparison.
• Keep high-risk tuning opt-in unless user explicitly requests it.
• Keep AMS assumptions explicit for each recommendation batch.
