Question about slow updates with Sanity client API

export const sanityClient = client({
  projectId: process.env.SANITY_PROJECT_ID,
  dataset: process.env.SANITY_PROJECT_DATASET,
  apiVersion: '2022-01-12',
  useCdn: false,
  token: process.env.SANITY_AUTH_TOKEN // Only if you want to update content with the client
});

const formattedInterests = interests.length ? interests.map(i => ({
            _ref: i._id || i._ref,
            _key: i._id || i._ref,
            _type: 'reference',
            _weak: true
        })) : [];
        const doc = {
            firstName,
            lastName,
            email,
            isSubscribed,
            age,
            tags: formattedInterests,
            city
        }
        const response = await sanityClient.patch(id).set(doc).commit ();
