Abstract: A method for visually displaying an indicator for preceding and succeeding source code lines being executed within a graphical debugging environment. The method includes displaying within a GUI source code lines for a segment of currently examined source code, displaying a visual indicator that is associated with a presently examined source code line, and determining a previously examined source code line, wherein the location of the previously examined line of source code is determined by the use of information that is associated with the previously examined line of source code. The method further includes displaying a visual indicator that is associated with the previously examined line of source code, determining a next source code line that is to be examined, and displaying a visual indicator that is associated with the next source code line that is to be examined.

Abstract: A method and apparatus is provided for analyzing performance of a computer or data processing system, during the time that a specified task is running on the system. The analysis is used to furnish a system user with a list of proposed hardware component upgrades that would improve system performance in various respects, each being accompanied by a parameter value indicating the improvement a particular upgrade would provide. Usefully, listed upgrades are made available over the Internet, for purchase by system users. In an embodiment directed to a method, for use with a computer system comprising a configuration of hardware components, selected hardware components are monitored as the system performs a specified task. This is done to acquire statistics representing the operation of respective selected components. The statistics are processed, to identify at least one selected component that impedes the system in performing the task.
