Review request for Asterisk Developers. Repository: Asterisk Description ------- The scheduler currently stores scheduled items in two ways: a hashtab and a heap. The heap is used for actually scheduling while the hashtab is used for fast retrieval under certain circumstances. In practice having the hashtab comes at a cost under normal use. Each time something is scheduled two memory allocations occur: one for the scheduled item itself and one for the hashtab. Each time something is rescheduled the hashtab entry is freed and allocated yet again. If you have a scheduled item which is rescheduled over and over this can be substantial. This change removes the hashtab usage and uses the heap for finding things. Diffs ----- /trunk/main/sched.c 405157 Diff: https://reviewboard.asterisk.org/r/3199/diff/ Testing ------- Ran scheduler unit test and also forced the scheduler to get used for Playback. Thanks, Joshua Colp
