Optomise for Speed or refresh - performance question?

[Antoine]

What is considered best when doing an application that allows you to browse
data eg by month?

I've currently got an app working so it does a complete refresh when you
change the month you are looking at, using a providers SDK tools. This is
reasonably effective - but there is a few seconds on jumping between one
month and the next (having optomised the rest of the app).

However I could change it to only refresh on command, and catch all the data
on first load. This might make the month jumps considerably easier and
smoother.

What is best? Allow for refresh or allow for speed?
I don't really fancy rewriting it all to force refresh (the data only
catches between a limited boundary so as it is currently, it doesnt get ALL
the data, only what is in the necessary time frame for the view).

Would most users prefer to see all the current data without ever having to
refresh, or is the performance loss to much of a sacrifice?

Is it likely as I anticipate to improve the performance by no end (the rest
of the code doesnt do that much except refer to the dataset caught from
xml).

Many thanks

Antoine,

Is this a Windows or Web application?

How often would the typical user view the data each day? Once, twice, or
over and over again?

How many records are there in a complete month's worth of data?

Hi Thanks for your question

Web app, but as in Intranet mostly

How often? Hard to say. As and when required most likely.

Number of records? As many as they have entered on the activities..

Cheers
Antoine

I have found this but I am not sure on some of the points, like whether data
caching would make sense or not. Perhaps I dont need datacahcing and I just
need to check is postback, and if the dataset is already created just use
that - though I doubt that helps with reusing session data on subsequent
session does it?
I have just tried triming the page size. I have viewstate disabled on any
fields I dont need it on and so on.
