Our Database Performance Audit & Telemetry Framework
We rely on deterministic query planner telemetry and memory buffer traces rather than trial-and-error indexing. Our four-tier diagnostic framework isolates bottlenecks without disrupting active production transactions.
Workload Profiling & Frequency Heatmaps
We aggregate slow query metrics via pg_stat_statements, MySQL Performance Schema, and Linux kernel I/O statistics to measure query frequency distributions, average execution times, and total server time consumption.
- Top-25 cumulative time queries
- Read/Write ratio breakdown
- Temporary file generation volume per statement
Execution Tree & Buffer Breakdown
We perform deep-dive EXPLAIN (ANALYZE, BUFFERS, VERBOSE) inspections on critical queries to identify sequential table scans, improper join algorithms (nested loop vs hash join), and inaccurate planner row estimations.
- Shared Hit vs Shared Read ratios
- Sort/Hash spill to disk (work_mem exhaustion)
- Filter condition implicit type casting
Lock Trees & Table Bloat Analysis
We evaluate row lock durations, transaction isolation levels, deadlock logs, index fragmentation, and MVCC dead tuple bloat across high-velocity transactional tables.
- Deadlock dependency graphs & PID locks
- Autovacuum freeze risk & scale factor calibration
- Index bloat & redundant duplicate index removal
Benchmark Validation & Remediation
Every proposed query rewrite, composite index creation, or parameter change is rigorously tested against staging replicas with before-and-after reproducible benchmark reports.
- Ready-to-deploy DDL & index scripts
- Query rewrite pull-request templates
- Live code review with client database architects
Zero-Trust Telemetry Intake Model
We believe client data privacy is non-negotiable. Our diagnostic procedures never require access to proprietary customer records or direct production write access.
Sanitized Query Digests
We analyze normalized parameterized queries where literal values, PII, and sensitive constants are masked at capture time.
Staging Replica Testing
Benchmark simulations and index builds are executed on anonymized staging clones or dedicated read-only replicas.
Client-Executed Migrations
Your internal database administrators execute the audited SQL scripts through your standard CI/CD deployment gates.
