    :SOC_RTC_FAST_MEM_SUPPORTED: - If using Deep-sleep mode, setting :ref:`CONFIG_BOOTLOADER_SKIP_VALIDATE_IN_DEEP_SLEEP` allows a faster wake from sleep. Note that if using Secure Boot, this represents a security compromise, as Secure Boot validation are not be performed on wake.
    - Setting :ref:`CONFIG_BOOTLOADER_SKIP_VALIDATE_ON_POWER_ON` skips verifying the binary on every boot from the power-on reset. How much time this saves depends on the binary size and the flash settings. Note that this setting carries some risk if the flash becomes corrupt unexpectedly. Read the help text of the :ref:`config item <CONFIG_BOOTLOADER_SKIP_VALIDATE_ON_POWER_ON>` for an explanation and recommendations if using this option.
    - It is possible to save a small amount of time during boot by disabling RTC slow clock calibration. To do so, set :ref:`CONFIG_RTC_CLK_CAL_CYCLES` to 0. Any part of the firmware that uses RTC slow clock as a timing source will be less accurate as a result.
-   :SOC_SPIRAM_SUPPORTED: - When external memory is used (:ref:`CONFIG_SPIRAM` enabled), enabling memory test on the external memory (:ref:`CONFIG_SPIRAM_MEMTEST`) can have a large impact on startup time (approximately 1 second per 4MiB of memory tested). Disabling the memory tests will reduce startup time at the expense of testing the external memory.
-   :SOC_SPIRAM_SUPPORTED: - When external memory is used (:ref:`CONFIG_SPIRAM` enabled), enabling comprehensive poisoning will increase the startup time (approximately 300 milliseconds per 4MiB of memory set) since all the memory used as heap (including the external memory) will be set to a default value.

 The example project :example:`system/startup_time` is pre-configured to optimize startup time. The file :example_file:`system/startup_time/sdkconfig.defaults` contain all of these settings. You can append these to the end of your project's own ``sdkconfig`` file to merge the settings, but please read the documentation for each setting first.
