Why does the redis-server take too long to load in memory the database at boot?

My Linux distribution uses the redis database. At boot the redis-server needs about 80 seconds to load the dataset. The following is a log that shows what I have written:

redis-server: 249:M 17 Oct 2022 16:29:55.173 * DB loaded from append only file: 79.442 seconds

If a Python program tries querying the database before the redis-server has finished the loading in memory operation, it is raised the Exception: redis.exceptions.BusyLoadingError. The Exception description is: Redis is loading the dataset in memory and is compliant with the context that I have described (that is the database is loading data in memory). Because I'm using the default configuration of redis-server in this moment I don't know exactly what is the type of persistence used by redis-server. The file redis.conf is very long so, here, I report settings that I think are most important:

...
########################### SNAPSHOTTING  ###########################
#
# Save the DB on disk:
#
#   save  
#
#   Will save the DB if both the given number of seconds and the given
#   number of write operations against the DB occurred.

# OE: tune for a small embedded system with a limited # of keys.
save 120 1
save 60 100
save 30 1000

######################### APPEND ONLY MODE #########################
# OE: changed default to enable this
appendonly yes

# The name of the append only file (default: "appendonly.aof")
appendfilename "appendonly.aof"
...

These settings (in particular appendonly yes) seem indicate that the persistence type used by the database is: Append Only File (AOF). I think these settings are causing this long loading time. Is it possible to use settings that avoid a too long loading time at boot?
