Thanks, I just noticed somethnig similar here:
http://www.powaibel.de/ojb/ojb-style/docu/objectcache.html One problem with some of the provider frameworks I've seen is that they use JCS in an inefficient way. JCS is based on cache regions, much like log4j. You wouldn't get a logger from the factory every time you wanted to use it. You'd get it from the factory and store it as a variable and then use it over and over. For instance, the framework in this article biases the results in this manner. OSCache doesn't have regions -- it's like a logger with one log, so there is no overhead in picking the region to use. . .. http://www.javaworld.com/javaworld/jw-05-2004/jw-0531-cache.html?lastpage=1#talkback I posted an explanation of why the times are biased. The last time I looked, hibernate did something similar. I haven't checked recently though.
