So, for instance, it starts with LRU and then the framework monitors the use of the cache and depending on the miss/hit rates and other information switches the algorithm accordingly??? That would be quite handy 38). An 'install and forget' kind of caching framework. Not sure if the monitoring would mean more overhead and then loose (some of) the benefit of caching.... Or would that be in part 3? - david Sat, 01 Aug 2009 01:22:06 +0100
