Correct. >> 2) When <parameter name="use-persistent-cache" value="true"/> do the >> cached objects go onto disk only when maxobjects is exceeded? > >Yes, as of currect CVS. No for the 2.0.1. Ahem yes of course for the 2.01 version too, or did I missed something here. That's only a flag. You answered this question in #1...or did I drunk to much beer tonight ;). >> 3) Is there any control over the number of objects on the disk? > >No. Persistent cache does not have such controls. You can extend its >implementation if you like. Correct, no control. Maybe we can implement something with the new Jisp based Filesystem store. It's possible to control the size of the dat file. >> 4) When the store-janitor decides to free memory, do the freed items >> go to persistent-cache or are they lost? > >Depends on store implementation. MRU store in the CVS uses persistent >cache to swap exceeding objects. Janitor does not care what store does >with extra objects. Again, I only see the main difference from 2.01 and CVS in the Jisp based Filesystem Store component.
