PERFORMANCE SUMMARY Observations Sharp rise in response time for over 50 users “Detail Page” degrades significantly for 75 users and above System is stable but peaks out at 75 concurrent users and starts degrading at 100 users Maximum throughput of 3.2 transactions per second at 75 users is low © Copyright PILLAR GLOBAL All rights reserved 3

RECOMMENDATIONS © Copyright PILLAR GLOBAL All rights reserved 8 Low throughput investigation –Check application/system level synchronization locks –Check server disk IO speed –Ensure sufficient RAM –Use GZIP compression of HTTP content –Use server farm with load balancer Slow “Detail Page” investigation –Check cache invalidation rules –Check available memory to cache subsystem –Check database indexes on query
