 # Deep Sleep Wake Stub Example

 > 2. The wake-up time shown in this example may be reduced by disabling the logs printed by ROM code. For most ESP chips, this ROM printing takes about 6100 us. In the product firmware, users can temporarily or permanently turn off ROM printing by calling ``esp_deep_sleep_disable_rom_logging`` or by setting ``menuconfig`` > ``Boot ROM Behavior`` > ``Permanently disable logging`` to speed up the wake-up.(ESP32 does not support suppressing ROM logging through menuconfig, but it can be suppressed by grounding GPIO15)
 
-> 3. Here is a method for roughly estimating optimal wake-up time: Taking ESP32-C6 as an example, the wake-up time from stub printing is about 6500 us. However, by substracting the ROM printing overhead of 6100 us and adding the system initialization overhead of 280 us, the wake-up overhead is estimated to be around 680 us. Users also can modify the example to configure GPIO wake-up and obtain a more realistic and accurate wake-up time by grabbing GPIO signals with a logic analyzer.
