As discussed in system performance, monitor disk activity, CPU and memory usage to determine whether the disk subsystems, processing speed or paging are limiting performance.

如系统性能小节所述，监控磁盘活动、CPU和内存使用量可以确定磁盘子系统、处理速度或分页是否影响了性能。

Using the example of storage space, the embedded Informix instance could be configured to monitor disk usage and add more storage when any DBspace consumes 80 percent of its allocated space.

以存储空间为例，可以通过配置嵌入式Informix实例监视磁盘使用量，当任何DBspace消耗了分配给它的空间的80%时，自动地添加存储空间。
