# Comparing Continuous Profiling Timeframes


  **Feature Availability**

  By default, Upsun offers 15 minutes of continuous profiling per project and for free.
To get 30 days of continuous profiling per project and for a fixed fee, [upgrade to the Continuous Profiling add-on](https://docs.upsun.com/administration/billing/add-on-subscription.md#continuous-profiling-add-on).

Upsun Continuous Profiler dashboard allows comparing two timeframes to better
understand application dynamics in various contexts.

You could compare two versions of the application, before and after a deployment,
or rush hours with quiet times for instance.

## Enabling comparison mode

A toggle on the top right corner of the continuous profiling dashboard enables
the comparison mode.

With comparisons enabled, you can select two timeframes referred to as ``A`` and
``B``. Those times can overlap.

## Understanding continuous profiling visual comparison

The flamegraph provides a visual representation of how timeframe ``B`` compares
to ``A`` for the selected dimension using shades of colors. The stronger the
color, the higher resource variation.

Shades of green indicates timeframe ``B`` is consuming less resources than ``A``
for the selected dimension. Shades of red indicate the opposite.

A scale and contextual information are displayed when hovering a span. This ensures
accessibility for all users and allow colorblind users to benefit from this feature.
