Redis bandwidth requirement calculator

This calculator helps you estimate the bandwidth required for your Redis instance based on the number of requests per second and the average response size.

Input Parameters

Calculation Results

Calculation Formula

Bandwidth Required (Bytes per second) = RPS × Average Response Size (Bytes) × (1 + Percentage of Read Commands)

Where:
RPS = Requests Per Second
Average Response Size = Average size of the response in bytes
Percentage of Read Commands = Percentage of commands that are read commands

Result

Bandwidth Required: N/A Bytes per second

Redis bandwidth requirement calculator Calculator Usage Guide

Learn how to use the Redis bandwidth requirement calculator and its working principles

How to Use the Calculator

  1. Enter the number of requests per second (RPS) your Redis instance handles.
  2. Input the average response size in bytes for your Redis commands.
  3. Specify the percentage of commands that are read commands (e.g., GET, KEYS). This helps in estimating the additional bandwidth required for read operations.
  4. Click the "Calculate" button to get the estimated bandwidth required.
  5. The result is displayed in bytes per second, giving you an idea of the bandwidth needed for your Redis instance.

Principle of Calculation

The calculator uses the formula:

Bandwidth Required (Bytes per second) = RPS × Average Response Size (Bytes) × (1 + Percentage of Read Commands)

This formula accounts for the additional bandwidth required for read commands, which typically consume more bandwidth compared to write commands.
