Database bottleneck causes response time spikes during high traffic

warning
performanceUpdated Jan 11, 2026(via Exa)
How to detect:

Without caching, every request hits the database directly, causing the database to become a bottleneck during traffic spikes. Response times increase significantly, potentially causing user abandonment.

Recommended action:

Implement caching using Redis or Memcached to serve most requests from memory instead of hitting the database. With proper caching, the database load remains stable even during traffic spikes and response times stay consistent.
