Java Portal Performance Optimization

I maintain a Java web portal built with JSP, Servlets, PostgreSQL, HTML / CSS, JavaScript and jQuery. Lately the system has become painfully slow. The heaviest delays show up in three places—login & authentication, database queries and general page rendering—yet the slowdown is not universal; it hits specific screens, namely the User Profile and Reports pages. Here’s what I need over the next few days: pinpoint the exact bottlenecks, tune the code or queries responsible, and deliver measurable speed-ups the moment we redeploy. You’ll have access to the full code-base, PostgreSQL schema and sample data so you can profile locally, propose fixes, and then apply them to the running instance. Deliverables • A concise diagnostic report explaining root causes on the affected areas • Optimised Java/JSP code, SQL, or front-end tweaks applied to the User Profile and Reports pages (including the login flow they rely on) • Any configuration changes or caching strategies needed, with clear rollback instructions If you’re comfortable profiling Java web apps and squeezing every millisecond out of PostgreSQL, I’m ready to get started right away.
