# Performance indicators ### Throughput Represents the number of TPS (i.e. transactions per second) a consensus algorithm can process. ### Scalability Represents the ability for a system to expand without degrading performance. Generally the throughput of a system is directly affected by scalability. ### Fault tolerance threshold Indicates an upper bound of faulty nodes that directly impacts the performance of the consensus algorithm. For example, some consensus algorithms have an optimistic regime that favors performance. ### Latency Also known as finality in this context, it represents the time it takes for a transaction to become settled in the ledger. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://tokens-economy.gitbook.io/consensus/performance-indicators.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
