Preview workflow is extremely slow

Hi, We are currently building an application that uses ChatGPT(api) and ElevenLab’s text to speech plugin. However, when we preview the page and run the entire workflow (which is essentially prompting ChatGPT and then reading aloud its answer), it takes a long time to process (around 10 seconds of silence) and output. Do you know what may the problem, and what we could do to fix it?
