+## Template Metrics
+
+Hugo is a very fast static site generator, but it is possible to write
+inefficient templates.  Hugo's *template metrics* feature is extremely helpful
+in pinpointing which templates are executed most often and how long those
+executions take **in terms of CPU time**.
+
+| Metric Name         | Description |
+|---------------------|-------------|
+| cumulative duration | The cumulative time spent executing a given template. |
+| average duration    | The average time spent executing a given template. |
+| maximum duration    | The maximum time a single execution took for a given template. |
+| count               | The number of times a template was executed. |
+| template            | The template name. |

+**A Note About Parallelism**
+
+Hugo builds pages in parallel where multiple pages are generated
+simultaneously. Because of this parallelism, the sum of "cumulative duration"
+values is usually greater than the actual time it takes to build a site.
+{{% /note %}}
+
+
+## Cached Partials
+
+Some `partial` templates such as sidebars or menus are executed many times
+during a site build.  Depending on the content within the `partial` template and
+the desired output, the template may benefit from caching to reduce the number
+of executions.  The [`partialCached`][partialCached] template function provides
+caching capabilities for `partial` templates.
+
+{{% tip %}}
+Note that you can create cached variants of each `partial` by passing additional
+parameters to `partialCached` beyond the initial context.  See the
+`partialCached` documentation for more details.
+{{% /tip %}}
+
+
+## Step Analysis
+
+Hugo provides a means of seeing metrics about each step in the site build
+process.  We call that *Step Analysis*.  The *step analysis* output shows the
+total time per step, the cumulative time after each step (in parentheses),
+the memory usage per step, and the total memory allocations per step.
+
+To enable *step analysis*, use the `--stepAnalysis` option when running Hugo.
