Avalon now incorporates a couple of modifiers for a Component definition that allows you to control the number of Components in a pool, and how quickly it grows. This is especially helpful in Cocoon where the defaults don't always work well. The magic attributes are "pool-min", "pool-max", and "pool-grow". The defaults are: pool-max: 8 pool-min: 2 pool-grow: pool-min (2) What this means is that the pool for the default component initially contains 2 instances, and if demand exceeds that the pool will increase by two components at a time up to 8 instances. Beyond that the pool turns into a factory in that new Component instances are created, but destroyed when they are returned. This is a performance issue--but it does manage the number of instances available at one time. For components like "event-pipeline" and "sax-connector", I would advise increasing the pool capacities to values like this: <event-pipeline pool-max="16" pool-min="8" pool-grow="2"/> <sax-connector pool-max="32" pool-min="16" pool-grow="4"/> There are no hard and fast rules. It is something that is worth playing around with. When you find settings that really work for you, post it on the list. The default settings work well for testing purposes, but in high traffic sites, they should be adjusted. Please note that if not specified, "pool-grow" always matches "pool-min". If not specified "pool-min" always equals "2". If you specify the minimum being higher than the maximum, then the maximum will match the minimum, and the pool will be fully filled on initialization. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
