Slow queries — sound familiar?

  • ▸ Galera flow control firing — wsrep_local_recv_queue spiking past the gcs_fc_limit threshold; flow control stops cluster-wide writes, p99 collapses, and you can't pinpoint the slow node.
  • ▸ Slow query log overwhelming disk — long_query_time at 0.5s and the slow log is rotating every 20 minutes; pt-query-digest analysis isn't scaling and the same patterns keep recurring after each 'fix'.
  • ▸ Query plan flip after upgrade — optimizer_switch defaults changed between MariaDB 10.5 → 10.11 / 11.x; queries that used to take 50ms now take 5 seconds because the join order regressed.

Why Choose Our MariaDB Performance Tuning?

We combine deep MariaDB internals expertise with a data-driven methodology to deliver performance improvements you can measure and sustain.

Expert Analysis

Our engineers have deep expertise in MariaDB internals, optimizer behavior, and storage engine architecture. We don't guess — we analyze execution plans, buffer pool statistics, and I/O patterns to pinpoint exact bottlenecks.

Data-Driven Approach

Every recommendation is backed by metrics. We baseline your current performance, implement changes incrementally, and validate each improvement with before-and-after benchmarks so you see exactly what changed and why.

Zero-Downtime Changes

We apply tuning changes using dynamic SET GLOBAL variables, online DDL for index operations, and rolling restart strategies with replica failover. Your applications stay online throughout the entire optimization process.

Measurable Results

We deliver a comprehensive performance report with quantified improvements: query latency reductions, throughput gains, CPU and I/O savings, and buffer pool efficiency metrics. Every optimization is documented and reproducible.

Our Performance Tuning Process

A systematic, four-phase methodology that delivers measurable performance improvements with zero risk to your production environment.

1

Assessment & Baseline

Capture current performance metrics, analyze slow query logs, review configuration, and establish baselines for query latency, throughput, and resource utilization.

2

Analysis & Planning

Identify top bottlenecks using EXPLAIN ANALYZE, optimizer traces, and Performance Schema data. Prioritize optimizations by impact and create a detailed tuning plan.

3

Implementation

Apply query rewrites, add or restructure indexes, tune buffer pools and thread pools, and adjust engine-level settings — all with zero-downtime techniques.

4

Validation & Handoff

Benchmark all changes against baselines, deliver a comprehensive performance report with before-and-after metrics, and set up ongoing monitoring dashboards.
