Bulk Submission Query to Azure

When implementing a user defined task I find the response times to be extremely slow even while using the bulk document submission in spacy-llm i.e. "list(nlp.pipe(docs))"

When using this technique I find that each document is submitted one at a time in a queue like structure as opposed to sending a bulk query to Azure and having the entire result returned at once? Is this the expected behavior? I have looked into Azure LLM api's and it does appear that they have bulk submission capabilities built into their system. I would love to be able to update my code in order to speed the processing time up with this implementation.
