Queues taking 25 seconds to be consumed in development. Why?

In local development, when I have an api route that triggers a queue using hono, and the consumer simply console logs the message, for some reason it has a delay of 25 seconds before all the console logs come printing out. Any idea on why that is? I would have thought it would be instant...? Code is written with hono.js This is my producer:

app.get("/test", async c => {
    const message = `Test message. Random number: ${Math.floor(Math.random() * 100)}`;
    await c.env.WEBSITE_QUEUE.send({
        body: message,
    });

    return c.json({ success: `Queued up this message: ${message}` });
});

app.get("/test", async c => {
    const message = `Test message. Random number: ${Math.floor(Math.random() * 100)}`;
    await c.env.WEBSITE_QUEUE.send({
        body: message,
    });

    return c.json({ success: `Queued up this message: ${message}` });
});

This is my consumer that simply console.logs the message

export default {
    fetch: app.fetch,
    async queue(batch: MessageBatch<{ body: string }>, env: Environment) {
        for (const message of batch.messages) {
            console.log(
                `Consuming message: ${JSON.stringify(message.body, null, 2)}`
            );
        }
    },
};

export default {
    fetch: app.fetch,
    async queue(batch: MessageBatch<{ body: string }>, env: Environment) {
        for (const message of batch.messages) {
            console.log(
                `Consuming message: ${JSON.stringify(message.body, null, 2)}`
            );
        }
    },
};

Nevermind, I figured it out. It's the max batch timeout settings in the toml file.
