Throughput — the real data transfer speed between the CDN node and the user. Measured in Mbit/s.
This metric is critical for:
Average download speed chart (cached/not cached) — two key scenarios. Cached — the speed of serving files from the CDN cache, reflecting the real performance of the infrastructure. Not cached — the speed when accessing your origin server. A large difference between the lines shows how important it is to configure caching correctly.
Cities with low speed — regions with congested uplinks or insufficient capacity of local nodes. Critical for the audience in these specific locations.
Providers with low speed — a comparative throughput ranking. A provider with spare capacity doesn't slow down during peak load hours.
