Start with the simplest possible locking scheme: lock the object-global
mutex at the beginning of each user-facing method. This is equivalent to
implicit locking provided by the reactor.
The reasoning behind this change is the incredible overhead of the
previous reactor request/response code:
Overhead for current model for every user-facing method:
- 2 struct type definitions (req/resp)
- 1 channel
- 1 struct member definition site
- 1 channel init site
- 1 struct population site
- 1 struct servicing site
- 1 struct closing site
- 1 actual execution method
New lock-based code:
Per object: 1 lock
Per method:
- 1 taking the lock
- 1 actual execution method
