Wenn Sie Bibliotheken von Dritten verwenden, die mit `await` aufgerufen werden müssen, wie zum Beispiel:

```Python

	azMeta := map[string]*string{}
	for k, v := range meta {
		azMeta[k] = to.Ptr(v)
	}
	resp, err := az.clnt.UploadStream(ctx, az.Bucket, az.getDest(object), io.LimitReader(r, length), &azblob.UploadStreamOptions{
		Concurrency: 4,
		AccessTier:  az.tier(), // set tier if specified
		Metadata:    azMeta,
	})
	if err != nil {
		return "", azureToObjectError(err, az.Bucket, az.getDest(object))
	}
	vid := ""
	if resp.VersionID != nil {

En ajoutant `standard`, Uvicorn va installer et utiliser quelques dépendances supplémentaires recommandées.

Cela inclut `uvloop`, le remplaçant performant de `asyncio`, qui fournit le gros gain de performance en matière de concurrence.

        if (offset + SIGNATURE_OFFSET + SIGNATURE_LENGTH > data.length) {
            throw new IllegalArgumentException("Signature field exceeds data buffer size");
        }

        // Use fine-grained locking for better concurrency
        this.signingLock.lock();
        try {
            if (this.closed) {
                throw new IllegalStateException("SigningDigest is closed");
            }

            // zero out signature field

/// tip

By adding the `standard`, Uvicorn will install and use some recommended extra dependencies.

That including `uvloop`, the high-performance drop-in replacement for `asyncio`, that provides the big concurrency performance boost.

When you install FastAPI with something like `pip install "fastapi[standard]"` you already get `uvicorn[standard]` as well.
