i am using the local embedding model - Could not load OpenAIEmbedding. Using HuggingFaceBgeEmbeddings with model_name=BAAI/bge-small-en. If you intended to use OpenAI, please check your OPENAI_API_KEY.
You can try with a better hardware, but the embedding it self doesn't have other solutions to improve speed, mainly this Langchain one, with OpenAIEmbeddings you would increase the batch size
