+# It's over 100 million!
+
+Tracy can handle a lot of data. How about 100 million zones in a single trace? Add a lot of zones to your program and see how it handles it!
+
+Capturing a long-running profile trace is easy. Need to profile an hour of your program execution? You can do it.
+
+Note that it doesn't make much sense to instrument every little function you might have. The cost of the instrumentation itself will be higher than the cost of the function in such a case.
+
+> [!TIP]
+> Keep in mind that the more zones you have, the more memory and CPU time the profiler will use. Be careful not to run out of memory.
+>
+> To capture 100 million zones, you will need approximately 4 GB of RAM.

+# First profiling session
+
+Let's start our adventure by instrumenting your application and connecting it to the profiler. Here's a quick refresher:
+
+1. Integrate Tracy Profiler into your application. This can be done using CMake, Meson, or simply by adding the source files to your project.
+2. Make sure that `TracyClient.cpp` (or the Tracy library) is included in your build.
+3. Define `TRACY_ENABLE` in your build configuration, for the whole application. Do not do it in a single source file because it won't work.
+4. Start your application, and * Connect* to it with the profiler.

+# Find some zones
+
+You can search for zones in the trace by opening the search window with the * Find zone* button on the top bar. It will ask you for the zone name, which in most cases will be the function name in the code.
+
+The search may find more than one zone with the same name. A list of all the zones found is displayed, and you can select any of them.
+
+Alternatively, you can open the Statistics window and click an entry there. This will open the Find zone window as if you had searched for that zone.
+
+When a zone is selected, a number of statistics are displayed to help you understand the performance of your application. In addition, a histogram of the zone execution times is displayed to make it easier for you to determine the performance of the profiled code. Be sure to select a zone with a large number of calls to make the histogram look interesting!
+
+Note that you can draw a range on the histogram to limit the number of entries displayed in the zone list below. This list allows you to examine each zone individually. There are also a number of zone groupings that you can select. Each group can be selected and the time associated with the selected group will be highlighted on the histogram.
