 VictoriaTraces provides the following prominent features:
 - It is resource-efficient and fast. It uses up to [**3.7x less RAM and up to 2.6x less CPU**](https://victoriametrics.com/blog/dev-note-distributed-tracing-with-victorialogs/) than other solutions such as Grafana Tempo.
-- VictoriaTraces' capacity and performance scales linearly with the available resources (CPU, RAM, disk IO, disk space). Also, it can scale horizontally to many nodes in [cluster mode](https://docs.victoriametrics.com/victorialogs/cluster/).
