Problem In Ceacceleratorcache

This message appears when enabling CEAcceleratorCache:

In my sharing host version of eaccelerator is: v0.9.6.1-ea

I noticed Yii documentation says:

what is the mean of above statement? and what is the problem?

It means that eAccelerator only supports caching of compiled code now, you can no longer use it to cache application data. That includes data that Yii might cache, such as database table schemata.
