I guess it means that many operations with some classes (in the java.util, this classes have to do with collections) state their performance, some spend constant time in searching, others, this time increases with the size of the collection!!!

do a search on Google for "Big O notation" -- constant time is part of that -- average / best / worse case for how long it takes an algorithm to do its thing (searching, sorting, etc)
