2019-07-31Use 1 byte hint for ar_table [Feature #15602]Koichi Sasada
On ar_table, Do not keep a full-length hash value (FLHV, 8 bytes) but keep a 1 byte hint from a FLHV (lowest byte of FLHV). An ar_table only contains at least 8 entries, so hints consumes 8 bytes at most. We can store hints in RHash::ar_hint. On 32bit CPU, we use 4 entries ar_table. The advantages: * We don't need to keep FLHV so ar_table only consumes 16 bytes (VALUEs of key and value) * 8 entries = 128 bytes. * We don't need to scan ar_table, but only need to check hints in many cases. Especially we don't need to access ar_table if there is no match entries (in many cases). It will increase memory cache locality. The disadvantages: * This technique can increase `#eql?` time because hints can conflicts (in theory, it conflicts once in 256 times). It can introduce incompatibility if there is a object x where x.eql? returns true even if hash values are different. I believe we don't need to care such irregular case. * We need to re-calculate FLHV if we need to switch from ar_table to st_table (e.g. exceeds 8 entries). It also can introduce incompatibility, on mutating key objects. I believe we don't need to care such irregular case too. Add new debug counters to measure the performance: * artable_hint_hit - hint is matched and eql?#=>true * artable_hint_miss - hint is not matched but eql?#=>false * artable_hint_notfound - lookup counts
