I have this code snippet but is taking too much to execute the query, but executing in the mongo console is executing in an acceptable time
 

for (const productId of productsGrouppedByCategory[group]) {
   const _id = Types.ObjectId(productId)
   ids.push(_id);
   const products = collection.find({ '_id': { '$in': ids }}, {'projection': {'priceHistory': 0}}).toArray()
   result.push(products)
}

I already updated the poolSize value, but nothing happens, it takes about 10 seconds to execute this query, when in the mongo console takes 4 seconds.
