Speed of application - Bandwidth costs

[mizzy]

Hi there,

My company has recently developed a browser based application. This is an inhouse development.
We use internet explorer to access the application.

We now find ourselves faced with a problem that all multinationals must face. We find that the application runs very very slowly over our intranet and we will have to spend large amounts of money on bandwidth to improve the responce times.

Is there anything we can do to improve the speed of the application before spending the money on bandwidth.
I have tried to use a proxy server but that actually slows things down instead of speeding it up.

I'm sorry that I cannot give you any technical information other than that the backend database is Oracle.

Regards,

Just a couple of general tips, really ...

1. Do as much of your processing as possible on or near the database box.
2. Just use your web server for transferring html.
3. Keep use of images to a minimum, and make image files as small as possible.
4. Keep pages as simple as possible consistent with enabling users to do their job efficiently.
5. lots of other things that I can't recall right now

Cheers, Mike.

Hi Mike

Thanks for the update.

Generally speaking I find that a proxy server speeds up access to the internet quite noticeably. (Due to the caching I guess)

Our new application is just another web site but when I try to access it via a proxy it slows down! In your experience have you ever heard of anyone using a proxy in this situation and improving responce times?

Regards,

p.s. when you say "web server for transferring html", what do you mean by web server? do you mean proxy server?

 

[HelloMike]

I mean whichever machine you use to deliver web pages to the user's browser.

Cheers, Mike.

Do all data validation on the client side (using scripting language like JScript or VBScript), as much as possible, prior to submitting form entries to the web server. Doing every validation on the server side (like checking if a field is empty or in the right format) is a waste of server resources, and slows it down unnecessarily.
