I have changed my app to use tapestry 5.4-alpha-22. Now the first page
load takes ~1 minute!
Subsequent page loads require ~1.5-2 seconds.
Hi,
a while ago I wrote here about assembly performance in our tapestry app
(The thread was titled "Speed up page compiling").
Unfortunately until now I did not found the time to track this or to
exctract a test case that shows the problem. Now I created a
minimalistic tapetry app that shows the problem:
If a Tapestry page consists of lots of components, the first page load
after a change takes lot of time. If you reload the page in the browser,
it loads incredible fast. So it's a problem that occurs during page
assembly.
The attached page uses only 18 unique components which are nested and
multiplied that way. This reflects a real-world application that
consists of lot of "high level" components (e.g. page parts) that are
assembled by using "lower level components" (e.g. forms or tables) which
are assembled by "low level components" like buttons, labels, ... which
bring their own css assets.
If I load the page the first time, it takes ~30 seconds on my machine to
assemble. Subsequent page loads takes <1 second until I change one of
the components or the page.
If I remove all css assets, loading time is reduced to ~10-15 seconds.
Do you see any chance to speed up assembly here (e.g. by introducing
some development cache or so)?
Regards,
Michael.
