Just create a DB with --db-type=DB_SUPER
rough explanation of its resource requirements?
minimum reqs are:
1.5~2x blockchain size of storage space
8+ Cores
1000MB/s read and 300MB/s sequential disk I/O
32GB RAM
8+ Cores

Are they real cores or do you mean 4 cores with hyper-threading?
Are the requirements lower if I will not implement DB_SUPER mode? I have only 16 RAM and 4 core wth hyper-threading.
