Which MPM best serves mixed static/dynamic workloads in Apache 2.4?

Goal

Determine which MPM module—mpm_event or mpm_worker—provides the best performance for a server that serves both static assets and dynamic content, after measuring the current bottleneck with Apache’s built‑in diagnostics.

Constraints

• Apache 2.4 with mod_deflate enabled for compression.
• KeepAliveTimeout set to the default 5 s, potentially tying up worker threads.
• Traffic pattern includes bursts of concurrent connections and long‑lived keep‑alive sessions.

Unresolved Decision

Official documentation does not recommend one MPM over the other for mixed workloads; the optimal choice depends on measured CPU, memory, and latency characteristics.

Questions

1. Can I use mod_status with ExtendedStatus On to separate CPU usage caused by mod_deflate from that caused by request handling?
2. Which MPM—mpm_event or mpm_worker—yields lower average latency when the server is under bursty traffic, given the current KeepAliveTimeout?
3. What measurement methodology should I adopt to reliably compare memory consumption and thread utilization between the two MPMs on my hardware?
