Slow uploads of files from the client browser to the R2 bucket using a presigned URL.

Hey guys, I notice slow uploads of files from the client browser to the R2 bucket using a presigned URL. Sometimes, the file upload also fails. The R2 bucket doesn't have public access and doesn't have a custom domain. Is this causing the issue? Are they rate limiting the upload requests? Do I need to assign a custom domain? Sometimes, when I send the PUT request to the presigned URL, it hangs and doesn't respond for 2-3 minutes. I tried to test with a 15MB file, but the issue remains the same.

Does enabling `nodejs_compat` in Cloudflare Workers slow down the worker's performance?

Is there any performance impact?

I am using Hono.js. I encounter an error when repeatedly sending requests, around 10 requests per second, through a middleware. In this middleware, I check if the user's IP is exceed limit in KV and then pass them through the route. The error arises during this process. Middleware

export const CheckLimitExceed = async (c: RequestT, next: Next) => {
    try {
        const { KV, ENVIRONMENT } = env<ENV>(c, 'workerd');

        const ip =
            ENVIRONMENT === 'development'
                ? '127.0.0.1'
                : c.req.header('x-real-ip') || c.req.header('cf-connecting-ip');
        const key = generateKvKey(ip);
        if (!key) {
            return c.json(
                {
                    success: false,
                    err: true,
                    message: 'Bad Request',
                },
                400
            );
        }

        const value = await KV.get(key);

        if (!value) {
            await KV.put(key, '1', { expirationTtl: expire_time });
            await next();
            return;
        }

        if (Number(value) >= PER_DAY_SHARING_LIMIT) {
            return c.json(
                {
                    success: false,
                    err: true,
                    message: `Limit exceeded for today. Please try again later.`,
                },
                403
            );
        }

        await next();
    } catch (err) {
        return c.json(
            {
                success: false,
                err: true,
                message: 'Internal Server Error',
            },
            500
        );
    }
};

export const CheckLimitExceed = async (c: RequestT, next: Next) => {
    try {
        const { KV, ENVIRONMENT } = env<ENV>(c, 'workerd');

        const ip =
            ENVIRONMENT === 'development'
                ? '127.0.0.1'
                : c.req.header('x-real-ip') || c.req.header('cf-connecting-ip');
        const key = generateKvKey(ip);
        if (!key) {
            return c.json(
                {
                    success: false,
                    err: true,
                    message: 'Bad Request',
                },
                400
            );
        }

        const value = await KV.get(key);

        if (!value) {
            await KV.put(key, '1', { expirationTtl: expire_time });
            await next();
            return;
        }

        if (Number(value) >= PER_DAY_SHARING_LIMIT) {
            return c.json(
                {
                    success: false,
                    err: true,
                    message: `Limit exceeded for today. Please try again later.`,
                },
                403
            );
        }

        await next();
    } catch (err) {
        return c.json(
            {
                success: false,
                err: true,
                message: 'Internal Server Error',
            },
            500
        );
    }
};

And pass that middleware like this: Route

router.get('/example/:id', CheckLimitExceed, getData);

router.get('/example/:id', CheckLimitExceed, getData);

BullMQ not working with cloudflare Workers!

const connection = new IORedis(c.env.REDIS_URL);
const sendEmailQ = new Queue('sendEmailQ', { connection });

const connection = new IORedis(c.env.REDIS_URL);
const sendEmailQ = new Queue('sendEmailQ', { connection });

Error

node_modules/bullmq/dist/esm/classes/child.js:2:23:
      2 │ import { Worker } from 'worker_threads';
        ╵                        ~~~~~~~~~~~~~~~~

  The package "worker_threads" wasn't found on the file system but is built into node. Are you trying to bundle for node? You can use "platform: 'node'" to do that, which will remove this error
