Q:

Javadoc tag for performance considerations

Is there a javadoc tag for performance considerations? 
One could imagine:
/**
 * ...other javadoc tags...
 * @perform Expected to run in O(n) time if image exists with O(k) memory usage
 */
 public Image getImage(URL url, String name) {
     //code goes here

If it is not built in, is there some de facto custom tag that people use?

A:

There isn't a standard, really. If you were to do this, just maintain a format you (or your org) prefers and keep consistent.
