Francisco Perez-Sorrosal commented on OMID-50:
----------------------------------------------

I think you have done the changes on top of the branch 0.8.2.0 instead of the current master. I've tried to apply the patch on the current master but it is not applied correctly. I´ve checked the contents and you made some changes in the /tso-server/src/main/resources/default-omid.yml file which does not exist anymore in master (now is /tso-server/src/main/resources/default-omid-server-configuration.yml) what means that you probably did the changes on the wrong branch.

> Currently tso-server use 300% cpu even at idle time. The reason for this 300% cpu usage is due to the BusyWaitStrategy used in disruptor. While this is good for throughput, it wastes resources in many use cases. In this ticket, I provide a config to use a different wait strategy and reduce the cpu usage with the option on.
