Hey Fengbin, did you run a program and noticed some kind of performance degradation because of this?
If yes, could you provide some details? If not, I would suggest to not do this. I can see how this "improves" performance in micro benchmarks, but not how it would affect the overall performance of the whole system with real programs running. – Ufuk On Wed, Aug 12, 2015 at 11:33 AM, Fangfengbin <fangfeng...@huawei.com> wrote: > Hello > > > > Some operators call system.currentTimeMillis() frequently and it is cost > performance. > > I want to use a thread to call System.currentTimeMillis and update a long > variable millTime.
