My Asterisk doesn scale. How about the CallWeaver software?
Yes, indeed, Asterisk doesn’t scale. Some of it has to do with an inefficient dialplan execution and pattern matching engine. We have made significant improvements to that and intend to replace the engine altogether with an efficient implementation. Another cause is a very naive implementation of internal storage using linked lists which is extremely inefficient. We are working on a replacement using hashtable storage. Yet another cause are locking issues. We have fixed quite a few locking related bugs, but to solve these issues properly, some structural changes in the core are necessary and we are working on that, too.
