If both the target utilization and allocation rate are high, the application can run out of memory, forcing the GC to run continuously and dropping the utilization to 0% in most cases.
如果目标利用率和分配率都很高,则应用程序可能耗尽内存,强迫GC连续地运行并且在多数情况下使利用率降低到0%。
In this case, the JVM tuning resulted in varying improvements for the three run time modes due to the unique object allocation patterns associated with each.
在本例中,jvm调优为三种运行时模式带来了不同程度的改善,因为它们分别采用所特有的对象分配模式。
Thanks to allocation groups, the XFS code will allow multiple threads and processes to continue to run in parallel, even if many of them are performing non-trivial IO on the same filesystem.
多亏了分配组,XFS 代码将允许多个线程和进程持续以并行方式运行,即使它们中的许多线程和进程正在同一文件系统上执行大规模 IO 操作。
