Performance diagnostics
We analyze critical queries, identifying inefficiencies in indexes, joins and schema design.
Database Performance Optimization and Tuning
We eliminate bottlenecks and latency in critical systems. We refactor PL-SQL and T-SQL to accelerate processes, reduce resource consumption and improve performance by up to 90%.

What's included
Key capabilities
At Vermont we don't solve this by adding more hardware. We analyze the system at a low level and optimize the code and database architecture.
Code refactoring
We rewrite PL-SQL and T-SQL procedures to improve performance and reduce complexity.
Monitoring and caching
We implement real-time analysis tools and caching systems (Redis) to reduce load.
Architecture optimization
We adjust system parameters to maximize CPU, memory and disk usage without needing more hardware.
Results
Critical processes that go from hours to minutes
The result: processes that go from 30 minutes to less than 5, freeing up resources permanently.

Observability to sustain the gains
Monitor HPC
When a query degrades again, you know before your users do. Monitor HPC provides continuous observability of critical processes with proactive alerts on performance degradation.

Do you optimize PL/SQL and T-SQL?
Yes. We refactor PL/SQL (Oracle) and T-SQL (SQL Server) by rewriting stored procedures, tuning execution plans, indexes and partitioning, and eliminating unnecessary cursors and loops in critical batch workloads.
What kind of improvement do you typically achieve in batch processes?
In financial and actuarial batch processes we have achieved reductions of up to 92% in execution time (from 15 minutes to under 1) and freed up 40% of server resources without adding additional hardware.
Do you work with Oracle Database and SQL Server?
Yes. We have deep experience with Oracle Database (all recent versions), Microsoft SQL Server and PostgreSQL, as well as Oracle-to-PostgreSQL migrations in banking environments under DORA.
Do you apply distributed caching such as Redis?
Yes. When the cost-benefit justifies it, we introduce Redis or another distributed cache to reduce pressure on the primary database, with invalidation and consistency strategies tailored to the system's access pattern.
What is an execution plan and why is it key to optimizing SQL queries?
The execution plan is the strategy the database engine chooses to resolve a query: which indexes it uses, in what order it joins the tables and whether it resorts to full scans. Analyzing the actual plan in production reveals the bottlenecks — missing indexes, outdated statistics or inefficient joins — and is the starting point of any serious optimization. Vermont Solutions always starts from the measured execution plan before rewriting a query.
