The size of some in-memory caches can be reduced. As caches trade off memory usage for performance, usually reducing these have a negative effect on performance.
-dbcache=<n>
- the UTXO database cache size, this defaults to450
(100
before 1.0.15). The unit is MiB (where 1 GiB = 1024 MiB).- The minimum value for
-dbcache
is 4. - A lower dbcache make initial sync time much longer. After the initial sync, the effect is less pronounced for most use-cases, unless fast validation of blocks is important such as for mining.
