Is 6-8 min of nursing too little?

I’m new to nursing , ftm, 2mpp. Just started nursing this week and my baby is only ever on my breast for 6-8 min, max 10-12 and usually longer than 8 min is just for comfort. Feeds about 9 times a day. Is that enough? Most people are talking about 20-40min each feed so I’m worried!
