DBCache is a setting that determines the level of RAM utilisation. The default is 1GB on V0.17.
Forcing this higher will see faster IBD since more RAM can store the UTXO set in memory to validate.

Prior to starting your client, amend dbcache=<RAM> where RAM should be around 80-90% of your available RAM in MB. Ie, if you have 4gb of ram, set dbcache=3600 in the config file, or run bitcoind --dbcache=3600 on startup
