Analyzing Live Set Trends

From the Trend tab, start analyzing your application. The types with the highest growth in bytes per second are marked red (darkest) in the Trend Analysis table and they are listed at the top of the table. For each update, the list might change according to the current object allocation and garbage collection rates.
