I have a webform with quite a few fields (between 15 to 40, based on user options). When user ends filling the form, I block it with jQuery.blockUI, and then on Server Side I process the form, packing it on an xml and call a new page. But transition between pages usually takes about 1 or 2 seconds, and I want to reduce it.
It’s possible to make all processing on the next page, as the data is then send to external web services and wait for a response. That takes up to 2 minutes, thus 1 or 2 seconds are less to notice there.
So, Is there a simple way to make all data processing, and still reduce transition time?
Thanks in advance
UPDATE: I’m pretty sure that would be the better aproach. But right know time is top priority, and I’m convinced that I know the bottle neck and have no little idea as how to solve or speed up the parsing of the data to an xml that has nearly 200 fields (about 50 come from the form, rest from queries or code).
On a side note, that 2 secs are come not only from data parsing, but from our slow out conection on the development server, and connection speed on Spain in general. I’m 80% sure that it won’t be as slow on the production server, but don’t want to run the risk of asuming that nothing can be speed up.
Then, the couple of minutes querying external web services is out of my hands. It contacts a provider’s webservice that links to a couple of Car Insurance companies, that get the data and throw out a list of insurance ¿prices? (sorry, don’t know the correct word). And as this is lost time I think I can hide that two seconds of XML construction here.
The only thing I don’t know is how to send form values from the Form to the Results page, that loads the data with Ajax.
I think you need to focus on why it takes so long processing 40 fields. What are the potential bottlenecks on the backend? What queries are you performing that take so long? If you can reduce the processing time to less than 10 seconds you can get away with your page handling the processing otherwise you need a different architecture like REST or NServiceBus to off load the long running execution and somehow notify the client that you are done.
