 ## Understanding a Trace
 
-`lighthouse-core/gather/computed/trace-of-tab.js` and `lighthouse-core/lib/traces/tracing-processor.js` provide the core transformation of a trace into more meaningful objects. Each raw trace event has a monotonically increasing timestamp in microseconds, a thread ID, a process ID, a duration in microseconds (potentially), and other applicable metadata properties such as the event type, the task name, the frame, etc. [Learn more about trace events](https://docs.google.com/document/d/1CvAClvFfyA5R-PhYUmn5OOQtYMH4h6I0nSsKchNAySU/preview).
