Running vector search directly alongside core business transactions can quickly degrade performance.

CYBERTEC helps tune database configurations so AI queries execute fast while operational workloads stay stable.

every UPDATE writes a new row version, and usually a new entry in every index. unless it's a HOT update: no indexed column changed and the new version fits on the same page. then the indexes don't get touched at all. fillfactor is how you leave that room.

Storage latency can easily bottleneck application performance.

PostgreSQL Asynchronous I/O capabilities boost read throughput under heavy concurrency, keeping system backends responsive.

A slow database query doesn't always need a bigger instance. Adding an index can make a query almost 300 times faster! #DatabaseOptimization #Indexing #PerformanceTuning 🐘🔍

Don't let runaway queries fry your CPUs. ⚡️

Catch long-running sessions and blocking locks early so DBAs can act before app response times drop. Our team at CYBERTEC uses proactive monitoring to keep Postgres pools running smooth.

I started surveying hundreds of Ecommerce sites via PageSpeed Insights, and found...

...well, the simulated findings are almost useless predictors of how real shoppers experience your site.

A PGConf presentation showed that properly tuned PostgreSQL can outperform Oracle at scale for a fraction of the licensing cost. The usual bottlenecks were checkpoint tuning, parallel query settings, and WAL configuration rather than raw hardware. #PostgreSQL #Database #PerformanceTuning

Cómo solucionar un alto consumo de CPU en SQL Server

Cómo solucionar un alto consumo de CPU en SQL Server Un consumo elevado de CPU en SQL Server no significa necesariamente que el servidor necesite más procesadores. Antes de ampliar la infraestructura, es fundamental identificar qué está utilizando la CPU y por qué. El diagnóstico debe comenzar diferenciando entre una carga de trabajo legítima y un comportamiento anómalo. Consultas con planes de ejecución ineficientes, recompilaciones frecuentes, estadísticas desactualizadas, paralelismo excesivo, funciones costosas o cambios en el volumen de datos pueden provocar que una carga habitual se convierta en un problema de rendimiento. Una de las primeras herramientas que debería utilizar un DBA es Query Store, complementada con DMVs y los planes de ejecución. Estas herramientas permiten identificar las consultas que consumen más CPU, comparar su comportamiento histórico y determinar si el problema está relacionado con una sentencia concreta o con la carga general del sistema. La solución tampoco debería ser simplemente aumentar el hardware. Optimizar una consulta, revisar índices, actualizar estadísticas, corregir un plan de ejecución o ajustar determinadas configuraciones puede generar mejoras mucho mayores y sostenibles. También es importante analizar cuándo ocurre el problema. Un pico de CPU durante un proceso programado puede tener una causa completamente diferente a un consumo elevado que se mantiene durante toda la jornada. Resolver problemas de CPU requiere medir antes de actuar. La experiencia del DBA resulta especialmente valiosa cuando combina métricas, planes de ejecución y conocimiento del comportamiento de la aplicación. La CPU es solamente el síntoma. Encontrar la causa es el verdadero trabajo del DBA. #SQLServer #DBA #DatabaseAdministration #PerformanceTuning #QueryStore #SQLPerformance #BasesDeDatos #MicrosoftSQLServer #Optimización #Tecnología Referencia bibliográfica interna Código: 2026081101 Área: Bases de Datos | SQL Server | Rendimiento y Optimización

This month, I have the honor of hosting T-SQL Tuesday #201, and I picked a topic that comes up on almost every client engagement I do: temp tables in tempdb. Should you use them?

#QueryFolding is a very important concept when it comes to #PerformanceTuning of #PowerBI and #PowerQuery solution

In today's video, I explained what it is and how it is important, using a demo
