Optimizing application performance and memory traffic with dotTrace

In this section, we are going to continue tracing our CH05_BatchFileProcessing project. We have fixed the UI freeze and will be running another trace to see whether we can identify any further issues. When analyzing the trace, we will see that a lot of memory traffic is being generated that is affecting the performance of our application. So, we will address this issue and fix it:
