I would like to ask another question (before looking to Eugene code): do >you use whole cache (128M) for current using table (it means only one table) or >do you divide that cache into small equal parts for all tables you have (say 10 >tables, each uses only 12M), or other way to use? It's pure LRU. If you are probing just one table most of the time, that will dominate the cache blocks. If you are probing many tables, then they all share the cache. There are no fixed "partitions" or anything in the cache.
