Description Milind Changire 2017-11-05 12:16:18 UTC

Description of problem:
On a service request, the actor is searched using an exclusive mutex lock which is not really necessary since most of the time the actor list is going to be searched and not modified.

COMMIT: https://review.gluster.org/18543 committed in master by  

------------- rpc: make actor search parallel

Problem:
On a service request, the actor is searched using an exclusive mutex
lock which is not really necessary since most of the time the actor
list is going to be searched and not modified.

Solution:
Use a read-write lock instead of a mutex lock.
Only modify operations on a service need to be done under a write-lock
which grants exclusive access to the code.
