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:
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.
