Proper way of syncing multiple addresses from code at once

Currently I am watching addresses I pass to my cloud function using a for loop which takes a lot of time to sync the data. Is there any sufficient way to like “bulk” sync addresses?

it shouldn’t take too much time, how many addresses do you try to add to watch?

2K +, whats already a little confusing to me is why my server peaks to 90% CPU at times with only 300 currently synced addresses. I am on the 200 USD per month server stack.

it should be possible to sync 2k addresses in ~10 minutes with running a script from nodejs, assuming that it is a nitro server, it will take some time after that for the data to sync
