How to speed up a page that uses data from a slow webservice

[Martin Tilma <m....@func.nl>]

Hi all,

I have a page and it's a bit slow and I want to speed it up, but don't
know a proper solution.

The case:

I have a page that contains 5 components showing different data
retrieved from a webservice. Each webservice call takes about 1 second.
Besides that I have 2 buttons who's visibility is based on data from
also the same slow webservice. In total there are 7 calls taking about 7
seconds to finish and to render the page.

I could cache the data, but that will only work the second time. I was
thinking about a way to preload the data and maybe use different threads
so the calls don't have to wait for each other...


Any ideays?

Martin

What about using AjaxLazyLoadPanel? Another solution could be: when page is
loaded, call from javascript a callback which will initiate an ajax call
responsible for updating each component. I did something similar, but using
other technologies (struts + dwr)... I think there could be similar approach
also with wicket.

in onbeforerender of the page you can execute the 7 calls you will
need in parallel and cache the data in fields.

if you want your page to feel more resposive you can present the user
with a busy indicator and using ajax feed back status messages or a
progressbar, once you have the data redirect to a page that presents
it.
