We discussed our biggest gains applied on bottlenecks found by using evidence. We found the evidence by using tools, most importantly: <A href="http://jakarta.apache.org/jmeter/">JMeter</A> for load testing, <A href="http://jamonapi.sourceforge.net/">JAMon</A> for performance monitoring and <A href="http://sourceforge.net/projects/jarep">JARep</A> for performance reporting. In this part we’ll deal with JAMon and JARep and lessons learned. </blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://architects.dzone.com/articles/case-study-performance-tuning--0"><P><B>Monitoring with JAMon</B></P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://architects.dzone.com/articles/case-study-performance-tuning--0"><div align="center"><img src="http://content9.clipmarks.com/blog_cache/architects.dzone.com/img/E8216FE8-CD6C-4A60-9D90-9E518CFFA86D" alt="" /></div></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://architects.dzone.com/articles/case-study-performance-tuning--0"><B>Figure 1.
