<p>Select the Threads tab to display the Thread Load. The Thread Load graph and related table show information about threads that were active during the selected time period. The graph and table show the CPU load separated according to the executed thread, independent of the binary or function in which execution took place. Figure 1 shows an example graph with the Threads tab selected.</p> |
