如果您在没有空闲cpu时或者在操作系统需要交换虚拟内存的地方试图优化服务器，则无法使其变得很快。

If you try to tune a server when there is no free CPU or where the operating system is swapping virtual memory, you won't get very far.

使用mount优化基于NFS服务器的资源，而这只有在挂载了NFS文件系统之后才能生效。

Use mount to tune NFS server-based resources, which take effect only after mounting the NFS file system.

我通常建议不要在一个服务器上放置两个或三个以上的队列管理器，因为这样做以后，操作系统的可优化性将开始受到影响。

I usually advise not putting more than two or three queue managers on a server, though, because after that the operating system tunables start to be impacted.
