Deep Dive

A CRM that is fast in testing with 5 users can be painfully slow in production with 500 users. Performance testing ensures your CRM maintains acceptable speed under expected load. Slow CRMs directly correlate with poor adoption.

  • Page load time (target: under 3 seconds)
  • Search response time (target: under 2 seconds)
  • Report generation time (target: under 10 seconds)
  • Dashboard refresh time (target: under 5 seconds)
  • Test with expected peak concurrent users
  • Simulate login storms (many users logging in at once)
  • Test concurrent report generation
  • Test with production data volumes
  • Test list views with 10,000+ records
  • Test search across large datasets
  • Test report generation with complex filters

Simulate typical daily usage patterns with expected concurrent users.

Simulate peak usage (e.g., Monday morning, month-end reporting).

Push beyond expected load to identify breaking points.

Run sustained load for 24+ hours to identify memory leaks and degradation.

  • Test on target devices (iOS and Android)
  • Test on slow network connections (3G simulation)
  • Test offline sync performance

If tests reveal performance issues:

  • Optimize slow database queries
  • Reduce dashboard widget count
  • Implement data archiving for old records
  • Review automation trigger frequency
  • Consider infrastructure scaling

We conduct CRM performance testing as part of go-live readiness assessments. Our testing covers response time, concurrent users, data volume, and mobile performance with optimization recommendations.

Never go live on a Friday. Never go live without a tested rollback plan. Never go live without dedicated hypercare for the first two weeks. These three rules have saved every project I've run.
