+# High Performance Mode
+
+WebSerial comes with an inbuilt High Performance Mode that optimizes data transmission for performance-critical applications. This mode should only be used when you require real-time logging and monitoring, as it minimizes latency and maximizes throughput by avoiding any kind of buffering for log messages.
+
+> [!NOTE]
+>
+> High Performance Mode should only be enabled when necessary, for example when your application is heavily dependent on large logs. Using this mode in scenarios where real-time logging is not required may lead to instability or performance degradation.

+    To enable High Performance Mode in Arduino IDE, follow these steps:
+
+    1. Open the `WebSerial.h` file located in your Arduino libraries folder.
+    2. At the top of the file, just after the `#include` statements, add the following line:
+    ```cpp
+    #define WSL_HIGH_PERF 1
+    ```
+    3. Save the file and restart your Arduino IDE to apply the changes.
+  </Tabs.Tab>
+  <Tabs.Tab>
+    You can easily enable High Perf mode by setting the build flag in your `platformio.ini` file.
+    1. Open the `platformio.ini` file of your project.
+    2. Add the following line under the `[env:<your_environment>]` section:
+    ```ini
+    build_flags = -DWSL_HIGH_PERF=1
+    ```
+    3. Save the changes to the `platformio.ini` file.
+    4. With PlatformIO, you can also further optimize AsyncWebServer *(used by WebSerial)* for high performance by adding the following additional build flags:
+    ```ini
+     -DCONFIG_ASYNC_TCP_QUEUE_SIZE=128 -D CONFIG_ASYNC_TCP_RUNNING_CORE=1 -DWS_MAX_QUEUED_MESSAGES=128
+    ```
