Even after you have fully synced the feeds, it takes gvm some time to ingest that data. I’ve seen it take anywhere from 15minutes to an hour depending on how much CPU/Memory you are throwing at it. I got around this by using docker and building an image that includes a recent full copy of the feeds as well as a fully functioning DB. You can spin up the scanner and have it ready to scan in 5-10 minutes or immediately if you skip the sync.
