Load testing is a method to measure your website or application’s performance under different conditions. It helps you understand how your system behaves under both normal and peak load conditions.The primary goal is to determine how many concurrent users can access your site while maintaining optimal speed for end users.
Load testing reveals potential bottlenecks before they impact your users in production. This proactive approach helps maintain service quality and user satisfaction.
Load testing helps identify critical issues that could impact your service:
System crashes under heavy load
Performance degradation
Scalability limitations
Resource bottlenecks
Prevent Downtime Before It Happens: Load testing helps you identify and fix performance issues before they affect your users. Don’t wait for your service to become popular to discover these problems!
Shows performance for slowest 5% and 1% of requests
Helps identify edge case issues
Error Rates
Tracks system failures
Indicates stability under load
Performance Trends
Response time patterns
User concurrency impact
Error rate correlation
Focus on P95: Pay special attention to the 95th percentile response times. If your slowest 5% of requests are problematic, you likely have scalability issues to address.
