Hello Akshat, thank you for your question. Generally speaking, we recommend following the suggestions in our documentation here:
https://www.gooddata.com/docs/cloud/connect-data/performance. I know this same question has been raised in the past, could you tell us if the suggestions there helped, or what changes did you introduce? Could you alsoprovide a concrete example? For example, insight ID or dashboard link? If you could provide a screencast or har file, please do so. This will help us greatly with our investigation. If you don’t feel comfortable sharing this information in the thread, feel free to send it to me via DM.
