dev.grpc-vs-rest Calculator
Calculates gRPC vs REST performance tradeoff from payload size, serialization overhead, and HTTP/2 multiplexing benefit. gRPC is typically 3–10× faster than REST for internal microservice communication — the binary protobuf encoding and HTTP/2 framing eliminate most REST overhead.
Inputs
Payload Kb
Applied force or weight (N or kN). Divide into dead load (permanent) and live load (variable — people, wind, etc.).
Requests Per Sec
Reference formula or conversion factor shown for context.
Serialization Ms
Reference formula or conversion factor shown for context.
Network Rtt Ms
Energy transferred by a force over a displacement (J = N·m).
Results
REST latency (ms)
Time from request initiation to response received. Composed of processing time, network round-trip, and queuing delay.
gRPC latency (ms)
Time from request initiation to response received. Composed of processing time, network round-trip, and queuing delay.
REST bandwidth (Mbps)
The computed width.
gRPC bandwidth (Mbps)
The computed width.
gRPC advantage
Sample size or count used in the calculation.
