In the last day of 2014, I will like to announce the 0.3 updates of VRQ solution for BFS.
It's almost a rework to address the lock dependency issues which caused by introduction of rq lock in VRQ. I'll like to do more clean up during 3.18 release, if it goes well, it will be moved to -gc branch.
Here are the test result of CFS, BFS original, Baseline(the VRQ based on) and the VRQ. It shows that after three release of VRQ, it can be better than original BFS in all kinds of workload and comparable against CFS(again? As I remember correctly, BFS is better than CFS in compiling test some release ago). But most important of all, VRQ open the opportunity to further improvements, I will give these new ideas a try next year.
Happy new Year 2015.
