Optimize performance by avoiding unnecessary computations, allocations, and operations. Use feature gates, lazy evaluation, and conditional logic to prevent work that won’t be used.

Key strategies:

  1. Feature-gated allocations: Only allocate memory when features are enabled
  2. Lazy computation: Defer expensive operations until actually needed and cache results
  3. Conditional processing: Skip loops and operations when conditions aren’t met
  4. Efficient data structures: Choose appropriate algorithms based on expected data size

Example of feature-gated allocation:

// Avoid allocating when feature is disabled
var shareIDs []structured.SharedDeviceID
var deviceCapacities []structured.DeviceConsumedCapacity
if a.enabledConsumableCapacity {
    shareIDs = make([]structured.SharedDeviceID, 0, 20)
    deviceCapacities = make([]structured.DeviceConsumedCapacity, 0, 20)
}

Example of conditional processing:

// Performance optimization: skip the for loop if the feature is off
if a.features.DeviceBinding {
    // Only do expensive work when needed
    for _, device := range devices {
        // ... expensive operations
    }
}

This approach is particularly important in hot paths, validation code that runs frequently, and resource allocation scenarios where unnecessary work can accumulate significant overhead.
