> 将新对象预留在新生代，由于 Full GC 的成本远高于 Minor GC，因此尽可能将对象分配在新生代是明智的做法，实际项目中根据 GC 日志分析新生代空间大小分配是否合理，适当通过“-Xmn”命令调节新生代大小，最大限度降低新对象直接进入老年代的情况。

另外，你还可以通过 **`-XX:NewRatio=<int>`** 来设置老年代与新生代内存的比值。
另外，你还可以通过 **`-XX:NewRatio=<int>`** 来设置新生代与老年代内存的比例。

比如下面的参数就是设置新生代与老年代内存的比值为 2（默认值）。也就是说 young/old 所占比值为 2，新生代占整个堆栈的 2/3。
