The Cache Hits sensor has detected a low percentage of disk cache hits.
A low level of cache hits compromises system performance because required data must be retrieved from the hard disk, rather than from the faster, RAM-based disk cache.
Close any non-essential applications. Consider adding RAM to your computer so that Windows can increase the size of your disk cache.
The trigger level for this sensor's alarm determines what Norton System Doctor considers a "low" percentage of cache hits. To change the trigger level, click Change Alarm Settings.
