Postback with no delay??

[Alex D.]

Recently I realized the Wachovia bank switched to asp.net pages. I like very
much the way they did it and I would like to know how they managed to do the
postbacks and the blinking between postbacks is almost unnoticeable!

I my sites even when browsing in the local network and the pages are very
very small I still can clearly see the blinking between pages postbacks (a
white page in the middle)

Is there any way I can do like wachovia?

Thanks,

Alex.

The postback is just "reloading" the page from the server. The amount of
time this takes will be a function of:

1) Your internet connection speed & your PC's speed
2) The size of the page you are trying to load
3) The internet connection speed and server speed of the host - in this
case, Wachovia Bank

There are lots of things you can do to speed up your pages such as:
- Frugal use of ViewState
- Careful management of server-side caching
- Disabling tracing and AutoEventWireup
- Precomiling pages, etc, etc

There are lots of great resources for this kind of thing - try Googling
"ASP.Net performance"

There are a couple of approaches if you are not running 2.0. XML-HTTP will
get you what you want however, the page will contain a lot of scripting.
Behaviors with the webservice htc implementation will do the trick nicely as
well. 2.0 supports script call backs and out of band calling that will
refresh portions of the screen. Note that these methods are still post backs
however, since the entire page does not need to be redrawn, it doesn't
*blink.

Thanks for your suggestions. But as I said my pages are reallyyy small (10k)
and I am accessing the site at full 100 mb/s in my intranet and I can still
see very clearly the blank page between postbacks. Also Wachovia pages dont
seem to use ajax since if you pay attention very close you will se that
actually the hole page is refreshing BUT like Firefox or Opera do ...not
like IE.

By the way, do you have a url to show us what exactly you are looking at? We
may have different experiences with the pages you are viewing.

1. Avoid viewstate like the plague. Unless really necessary.
2. Use light weight objects such as the repeater instead of the datagrid or
gridview. I guess Microsoft thinks everyone is running top of the line
machines for their servers.
3. Avoid session state all together. Session slows the performance of the
machine running the web app. Hidden fields is an alternate.
4. Enable Content Expiration for the web site.
5. Use datareader instead of dataset or other bulky objects for data access.

There are many other performance tuning techiques available. Google building
performance driven applications using asp.net. That should get you some good
reading material on the subject. It really is an art itself.

maybe you are right and the datagrid is causing the problem. the page I was
using to make tests just have a label and a colorfull datagrid. also maybe
using soft colors will smooth the transition between pages.

unfortunately the site I am talking about is already in use and is private.
but as I tried with opera and firefox and they perform MUCH better than
IE....but MUCH better to the point that you dont see the postbacks blinks at
all!!

Nah, colors have no bearing on performance. It may only assist in an illusion
that there is no blinking (e.g. white page background versus a dark page
background). But that has nothing to do with performance.

Another thing, don't have images if possible. Some sites i've created have a
brand or logo and thats fine. But I stay away from using images if I can.
That is less info that has to be downloaded to the client.

Again, there are many articles on this subject. I pay attention to those
written by microsoft since they know the "under the hood" better than others
would. MSDN Magazine, and MSDN, as well as Patterns and Practices.

> 1. Avoid viewstate like the plague. Unless really necessary.

3. Avoid session state all together. Session slows the performance of the
machine running the web app. Hidden fields is an alternate. These recommendations are not correct and very contrary to MS best
practices. In particular, hidden fields should be avoided. The session
recommendation refers to old literature based on classic asp sites. There is
nothing inherently wrong with viewstate. Dino Esposito's book on asp.net is
a resource for building scalable web architecture.
5. Use datareader instead of dataset or other bulky objects for data
access. This recommendation is often very misleading as well and certainly needs
qualification.

ViewStates can get very large. DataGrids, for example, appear to store
their DataSets in ViewState. I've seen ViewState approach 100Kbytes in
size, which even under ideal circumstances is over a second and a half
on a 512Kbit DSL connection.
