我试图了解我对云存储性能的期望。
我刚刚从与我的云存储桶位于同一位置(美国)和同一项目的计算引擎实例运行了 gsutil perfdiag。
对于近线存储，我的读取速度为 25 Mibit/s，写入速度为 353 Mibit/s，这是低/高/平均值，为什么读取和写入之间存在这种差异？

############## = 1.6最佳答案
在所有条件相同的情况下，现代存储系统的写入性能通常更高，因为应用程序磁盘之间存在缓存层，也就是说，您看到的内容在“近线”存储的预期范围内。
在使用“标准”存储桶时，我观察到了非常出色的吞吐量结果。虽然延迟并没有改善多少。如果您的应用程序需要高吞吐量，请考虑使用“标准”存储桶。如果您的应用程序对延迟很敏感，那么使用本地存储作为缓存(或暂存空间)可能是唯一的选择。
这是我在“标准”存储桶上的一个实验的片段:
