# Increasing caching
# This has potential to increase memory usage to 110m under heavy usage, but
# I find that unlikely as almost everything is using so short TTLs
# See also MEMORY CONTROL EXAMPLE in man unbound.conf

server:
    # bytes in message cache, defaults to 4m
    msg-cache-size: 50m
    # bytes in rrset cache, defaults to 4m
    rrset-cache-size: 50m

    # Cache results for 15 minutes even if they had a shorter TTL. Cloudflare
    # zone export used to have 1 second, and I have also been seeing 1
    # minute in the wild, I think 5 mins shouldn't break anything, but bigger
    # might.
