My AWS-hosted WordPress site sits on an EC2 instance and hovers at 90-100 % CPU even during moderate traffic. I have not pinned the problem on any particular plugin or theme yet, and the usual quick fixes—restarts, light plugin pruning, basic database cleanup—haven’t moved the needle. I now need a thorough investigation that goes beyond guess-and-check so the site can run smoothly again. Here’s what I expect: • A systematic audit of server metrics (top/htop, CloudWatch, WP-CLI debug, error logs) to isolate the code, query, or configuration that is eating CPU. • Clear evidence of the root cause—whether it’s an expensive query, a runaway cron, an un-cached API call, or something inside a theme/plugin. • Actionable optimizations implemented: code tweaks, plugin/theme re-configuration, object/page caching, database indexing, or server-level tuning as needed. • A short report that sums up what was found, what was changed, and baseline numbers showing the CPU drop and faster page loads. Acceptance criteria: average CPU stays comfortably below 30 % under current traffic, no site features regress, and the changes are documented so I can maintain them. Comfortable working directly on AWS (EC2, RDS, CloudWatch) and familiar with WordPress profiling tools like Query Monitor or New Relic? Let’s get this site breathing again.
