RE: where can caching help performance?

Hi Jamie, Even when using Struts there is nothing stopping you writing a custom tag lib to do a db lookup for your portals content, based I guess upon a user preference held in the session/request. You could then use the caching tags you describe. Also remember that most dbs have very good conf

RE: where can caching help performance?

on the topic of cache freshness, one idea that I thought was interesting was something IBM was reportedly doing for the Olympics (or some other very high-traffic) website. Changes to the data in the database triggered messages to the cache to invalidate certain cached objects. This removes then

RE: where can caching help performance?

We have found that the biggest bang for the buck comes with pre-fetching data out of the database and building our business objects ahead of time and storing them in an in-memory cache. This means that we have a very large cache (we estimate at least a gig when we get fully ramped up for phase
