Title: Cognos Performance over Internet
Post by: bjornidren on 02 Jul 2010 03:17:04 AM
Hello Everyone.

We recently deployed Cognos BI 8.4.

Setup is as follows:
Servers running on Linux Redhat and db used is an oracle 11g.

We have a dashboard and 5-6 standard reports that are query prompted reports.

Servers are in Europe, running over internet from any country in Europe works fine.
Of course speed and latency of your Internet connection comes into play, but it sort of similar speed as loading any kind of internet newspaper frontpage.

But, people sitting in the US or Australia or India get 10 times loading times, even for firing up a prompt page before submitting a report.
Working in query studio is more or less impossible.

We tested with different Internet pipes US<>Europe but it does not seem to be the issue.

Most logical reason would of course be latency/speed but we cannot seem to pinpoint it to that.
It behaves more like a timeout, but why would a timeout come into play from some countries but not others.

Anyone have any ideas?

I have noticed that with older browsers and/or web servers the application is very "Chatty" with a high latency this can lead to time outs.

Try running Firefox 3.6.3 or Internet Explorer 8. IE 6 is definitely a no-go.
