This page shows performance metrics for the cid.contact InterPlanetary Network Indexer. We gathered the data with our Tiros measurement tool.

Trends #

The graph shows different percentiles of the “Time To First Provider Record” (TTFPR) metrics over time. To measure the TTFPR, we start the stopwatch right before we do the https://{ipni}/cid/{cid} HTTP request to the indexer and stop it when we have received and parsed the full record.

In the above graph we aggregate these latency measurements on a daily basis and calculate the 50th and 90th percentiles incorporating data from multiple regions. In our measurement setup, we do multiple requests for the same CID. To differentiate between cached and uncached latencies, we show the latencies of the first requests for a CID as “uncached” and subsequent request latencies as “cached”.

It is important to note that the resulting TTFPR percentiles are artificial composites and do not reflect the specific performance of any individual region. Rather, it allows to discern general tendencies and fluctuations in TTFPR across the combined dataset. By focusing on these overall trends, we can gain valuable insights into the performance of IPNI TTFPR performance as a whole, making it easier to identify any notable deviations or improvements in that metric over time.

Lookup Latencies #

The graphs presented below display the latencies for the “Time To First Provider Record” (TTFPR) observed from various regions over the past few days. Each line represents the Cumulative Distribution Function (CDF) of the lookup latency in a specific region. Note that the x-axis is presented in a logarithmic scale. We distinguish between two types of latencies: uncached, which refers to the first request for a CID, and cached, which pertains to subsequent requests for a CID.

DHT Comparison #

The bar chart above illustrates the 90th percentile of latency associated with looking up a provider record using two different methods: the Distributed Hash Table (DHT) and this network indexer.

The network indexer’s lookup latencies are divided into two categories: uncached and cached latencies. When a CID is looked up for the first time, the response is cached at the edge. The “uncached” latency bars indicate the latencies for initial CID lookups, while the “cached” latency bars represent the latencies for subsequent lookups.
