Assistance is given to aid in optimizing a program's performance during initial development while the program's features are still being implemented and/or debugged, without interfering with that development, by providing easy-to-ignore yet accurate tips about a program's performance inside a debugger. Raw performance information for a software program which is being debugged in a debugger is adjusted by removing from it a measured debug overhead or other diagnostic overhead. Some factors considered when measuring overhead include pauses, context switches, debug versus release build presence, bounds checking, funceval, and call stack analyses. The debugger is enhanced to display the adjusted program performance measure in a graphical user interface, next to the corresponding source code. The enhanced debugger updates the adjusted program performance measure value and keeps its screen location current as the developer moves through the source code, providing more detailed performance information upon request.

Activity-based sampling provides useful and relevantly focused diagnostic data, connected to improve a developer's understanding. An application invokes log-event procedures, causing a logger to check logging conditions and make a log entry when a logging condition is satisfied. The logger has a set of log-enabled activities, and one or more start-events with respective sampling frequency conditions. One logging condition is that a current activity-id be log-enabled. Another states that if the current activity-id is not log-enabled but the log-event procedure identifies a start-event consistent with the sampling frequency condition, the activity is log-enabled and a log entry is made. Creation of a child activity by a parent activity which is in the set of log-enabled activities is noted in the log, and the child is automatically log-enabled. A log consumer may reside inside or outside the application. Event Tracing for Windows services can be enhanced to support activity-based sampling.
