OK that's me again... It seems that I have solved the problem; you have
to a
cache value, something like:

 $DB_HASH -> {'cachesize'} = 10000000;
    tie %h, "DB_File", "filename", O_RDWR|O_CREAT, 0640, $DB_HASH
        or die "Cannot open file 'filename': $!\n";

Only one more question: in which value the cache size is expressed?
thanks to all again!
