How to Pinpoint Memory related performance bottlenecks

The basic symptoms of memory related performance problems are -

1. Memory leak

• Memory usage slowly increases over time
• Performance degrades
• Application will freeze/crash requiring a restart
• After restart application is running fine again, and the behavior continues

2. Excessive memory footprint

• Application is slow to load
• After load, other application runs slower than expected

3.  Inefficient allocation

• Application performance suddenly degrades and then recovers quickly
• % Time in GC Statistic in PerfMon is greater than 20–30%
