### In-memory path finding
Finding a path through the channel graph for sending a payment doesn't involve
any database queries anymore. The [channel graph is now kept fully
in-memory](https://github.com/lightningnetwork/lnd/pull/5642) for up a massive
performance boost when calling `QueryRoutes` or any of the `SendPayment`
variants. Keeping the full graph in memory naturally comes with increased RAM
usage. Users running `lnd` on low-memory systems are advised to run with the
`routing.strictgraphpruning=true` configuration option that more aggressively
removes zombie channels from the graph, reducing the number of channels that
need to be kept in memory.
