Tune Chronik

You can tune Chronik to speed up indexing with the parameters below.

Warning

This is advanced usage — defaults are usually best. Incorrect settings can slow down indexing.

TxNumCache

When resolving tx nums of spent outputs, Chronik uses a TxNumCache. By default it uses about 40MB; you can increase usage if you have spare RAM.

  • -chroniktxnumcachebuckets — number of buckets (default 10). Too high can slow indexing because buckets are scanned linearly.
  • -chroniktxnumcachebucketsize — txs per bucket (default 100000).
