To survivor区的空间不足,再次晋升到old gen区,而old gen区内存也不够的情况下产生了promontion faild从而导致full gc.那可以推断出:eden+from survivor < old gen区剩余内存时,不会出现promontion faild的情况,即: (Xmx-Xmn)*(1-CMSInitiatingOccupancyFraction/100)>=(Xmn-Xmn/(SurvivorRatio...
but also reduce the total number of global safepoints arbitrarily injected, as mentioned before, by the JVM. This means that overall latency would reduce substantially. Interestingly, this blog (http://epickrram.blogspot.in
