说明
目标：
使 vCenter Server Appliance 保持可接受的性能和资源使用水平。事实：
vCenter Server Appliance

Performance
vCenter Server Appliance Management Interface （VAMI）Process：CPU Performance
vCSA should not than constant CPU usage of 70%.
如果 VPXD 进程占用大部分 CPU 并且超过 70%，请考虑以下建议：
向 vCSA 添加更多 CPU。
添加更多 vCSA 实例以平衡 vCSA 实例之间的负载。
如果 Java 服务占用了大部分 CPU，则应增加该服务的堆内存大小。内存性能
vCSA 不应超过 70% 的恒定内存使用率。
如果内存使用率持续超过 70%，则执行以下作：
验证是否正在交换 vCSA。请参阅 VMware 文章中的信息：内存性能问题的解决方案
验证哪些服务的 CPU 使用率较高。
高 CPU 使用率可能表示交换过多，因为需要 CPU 来处理交换作。
如果高使用率一致，则可能需要添加内存。
如果群集中的内存过量使用，请考虑为 vCSA 设置预留。
使用 VAMI 监视 CPU 和内存使用情况

或者，
使用 PuTTY 会话登录到 vCSA shell。
发出命令并查看 CPU 和内存的指标。

查看服务堆大小
vCenter Server 由多个 Java 服务组成。Java 服务使用堆（预先保留的内存）来存储数据对象。适当的堆大小对于最佳性能非常重要。在以下情况下，vSphere UI 可能需要更大的堆大小：
增强型链接模式下的多个 vCenter Server 实例
许多扩展和插件
大量库存
如果您主要使用 CIFS/NFS 来写入备份，则应使用

如果由于性能问题而必须更改服务堆大小，请参阅 VMware 文章：手动增加 vCenter Server 组件上的堆内存
