Thank you, this is really important! I’m glad that many ideas for improvement that were considered on the forum are still considered by Storj. For reference I’m linking some of the posts that discussed them.
I’ve got my own patch that updates bandwidth.db as orders are sent, based on data from the orders file. It also aggregates data before inserting, so that the database has less to do. I haven’t actually measured how much, or whether it helps. I’m not running it on my nodes either. Though, I believe this would be the cheapest way of implementing this feature.
Comparison of these alternatives would certainly be interesting!
