Optimize your databases with the co-developer of the leading tool
Leverage elite MySQL & MariaDB expertise led directly by Jean-Marie Renouard, a key contributor to MySQLTuner-perl, the diagnostic tool executed on millions of servers worldwide.
The Story of MySQLTuner-perl and our contribution
Created to simplify MySQL administration, MySQLTuner is a Perl script that has become the absolute global standard for auditing live MySQL and MariaDB configurations. It has millions of downloads and is used daily by sysadmins and hosting providers worldwide.
As a co-developer and major contributor to the tool, Jean-Marie Renouard actively maintains its optimization rules (InnoDB engine, memory management, indexing, and security) to support the latest database engine versions (MySQL 8.x, MariaDB 10.x/11.x).

- Advanced interpretation The tool returns recommendations, but only an expert eye knows how to correlate indicators to avoid catastrophic side effects.
- Custom tuning Precise tuning of InnoDB variables (buffer pool, log file size) and Linux kernel parameters for your specific workloads.
- Control, testing & Coherence Index auditing, SQL profiling, automated regression testing, and replication consistency checks.
Why database monitoring is critical today
Cloud Cost Optimization
Inefficient configuration or missing indexes force database instances to over-provision RAM and CPU on AWS RDS or GCP. Tuning your DB instances slashes your infrastructure bills.
Control & Data Coherence
Untested schema drifts and query bottlenecks cause critical inconsistencies. Test automation and structure audits restore total control over your production environment.
Security & Compliance
Default database configurations often leave dangerous vulnerabilities. We audit system privileges, secure network traffic, and patch loopholes to ensure GDPR compliance.
Proactive Management
Stop operating in firefighting mode. We implement modern observability tools (Grafana/Prometheus) to detect memory leaks and growth patterns before they cause outages.
Our interventions on your MySQL & MariaDB databases
InnoDB Configuration & Tuning
Full review of MySQLTuner global variables and deep customization (InnoDB Buffer Pool, Log Files, tablespace settings, SSD/NVMe optimal parameters) tailored to your Linux OS.
Indexing & Slow Query Profiling
Detailed analysis of the Slow Query Log, query profiling using EXPLAIN, removing redundant indexes, creating composite indexes, and rewriting inefficient SQL queries.
High Availability & Scalability
Design of highly resilient database topologies: setting up Master-Slave replication, multi-master MariaDB Galera clusters, and smart routing/load-balancing using ProxySQL.
