Well, we have a large app that is not performing very well.. and now I
have to figure out how to make it more performant..
And I was just wondering if dumping component level response times,
could maybe give me some sort of clue as to what to focus on.. It's a
slightly different view of the code and work being done, instead of at
method response times.. because there is no one method for rendering a
component or page, etc..
so, just a thought.
I guess I can tweek ComponentPageElementImpl to add extra
RenderingEvents to do this.. interesting..

Acutally, check the logging documentation; there's already a service
that times how long the render takes and how many render operations
were involved. Much of the performance improvements in 5.1 was reduce
the number of operations per component.
There isn't a good way to get output about time per component; that
time would be very short & hard to measure.
Why are you interested in component render times?

out the render time for each component..
that way I can use that information to try to pinpoint components that
need to be optimized..
Quick and lazy :) answer: try to find the tapestry-core service that renders
components and decorate it using AspectDecorator . . .
I hope it helps . . .
By the way, AspectDecorator is absolutely awesome.
