This is a major redesign a modernization of Sysprof. The core data structures and design are largely the same, but it has been ported to Gtk3 and has lots of additions that should make your profiling experience smoother. Especially for those that are new to profiling. There are some very simple help docs added, but we really need the experts to come in and write some documentation here.

<title>What is a Profiler?</title>
|
|
|
|
<p>A profiler is an application that records information about an
|
|
application or system while it runs. That information can be explored to
|
|
gain insight into how the application could be changed to perform
|
|
better.</p>
|
|
|
|
<p>Two common categories of software profilers exist, commonly referred
|
|
to as either tracing or sampling profilers. What is meant by tracing
|
|
profiler is that every function call executed by the program is known to the
|
|
profiler. A sampling profiler works by inspecting the state of the
|
|
program on a regular frequency and therefore does not see every function
|
|
call executed by the program.</p>
|
|
|
|
<p>Both tracing and sampling profilers have their advantages. A
|
|
notable advtantage of a sampling profiler is that the overhead is much
|
|
less than that of a tracing profiler, making it easier to use for
|
|
software that requires interactivity.</p>
|
|
|
|
<p><app>Sysprof</app> is a sampling profiler.</p>
