Question for return size of PageFilter

[whodarewin2006]

hi,all
    I am using PageFilter to limit the return record from hbase,but I found 
that the record amount that returns from hbase is more than the amount I set to 
PageFilter,I read the annotate ,it said the PageFilter is applied separately on 
different region servers,and return regionserver amount*limit size count 
record,so the question is : can we optimize the PageFilter that return the  
size we want?
