Database · Performance Tuning

Lower latency and a lower bill — at the same time.

Slow queries and oversized instances usually travel together. We profile the real bottlenecks, fix them at the query and schema level, and right-size what's left — on AWS, and multi-cloud when you need it.

What's included

Find the bottleneck. Fix the cause.

We tune the layer that's actually hurting — not whatever's easiest to change.

Query optimization

Explain-plan analysis on your worst offenders, rewritten for the planner — often 10× faster with no app changes.

EXPLAINpg_stat_statementsQuery Insights

Indexing & schema

The right indexes added, the redundant ones dropped, and partitioning where the data volume demands it.

Connection pooling

Pooling and proxying to survive connection storms, plus read replicas to offload reporting traffic.

RDS ProxyPgBouncerRead replicas

Right-sizing

Instance class, storage type and IOPS matched to real load — so you stop paying for headroom you never use.

From firefighting to headroom

We start with a profile of where time and money actually go, fix the top offenders, and leave you with the dashboards to keep it that way. No guesswork, no blanket "add more RAM."

  • Top-20 slow queries profiled and fixed first
  • Index and config changes validated on a replica
  • Latency and cost dashboards handed to your team
