Ideal RSS polling limit

Hi guys I use a discord rss bot "MonitoRSS" to scan my lemmy inbox rss feed every 10 minutes to sort of replicate push notifications for ios and android.

Is this poll rate to high or acceptable?

Additionally would increasing the referesh rate to every 1 min consume to much bandwith/harm the server?

Curious on your thoughts (not sure what entails fair use).
