Struct AimdConfig 

Source 
pub struct AimdConfig {
    pub initial_rate: f64,
    pub min_rate: f64,
    pub max_rate: f64,
    pub decrease_factor: f64,
    pub additive_increment: f64,
    pub window_duration: Duration,
    pub throttle_threshold: f64,
}
Expand description

Configuration for the AIMD rate controller.

Use builder methods to customize. Defaults are tuned for cloud object stores and will start at about 40% of the max rate and require 10 seconds to reach the max rate.

  • initial_rate: 2000 req/s
  • min_rate: 1 req/s
  • max_rate: 5000 req/s (0.0 disables ceiling)
  • decrease_factor: 0.5 (halve on throttle)
  • additive_increment: 300 req/s per success window
  • window_duration: 1 second
  • throttle_threshold: 0.0 (any throttle triggers decrease)
