OPCache is a robust tool that enhances PHP performance, making web applications faster and more efficient. Included as an extension in PHP, OPCache stores precompiled script bytecode in shared memory. This eliminates the need for PHP to load and parse scripts with each request, significantly reducing execution overhead and improving server response times. This not only enhances the user experience but also reduces server load, allowing it to handle more requests at once. OPCache's benefits are especially noticeable in high-traffic environments where performance and efficiency are critical.

The Doom melody requires more memory than others, so make sure your board can handle that amount. If not, you will usually encounter an error during compilation.

As a workaround, you can try removing some of the notes (along with their respective durations) to fit the melody on the board.
