Thanks for replying, Rob.
I am talking about Network bandwidth and I've seen in the forum references to the option to compress network traffic, but my question is not based on a problem that QlikView is too slow; but rather, a request from 2 customers who are doing a sizing analysis of QlikView.
There is a format to estimate the RAM or CPU necessary to support a certain data source size or number of users, but the customers also want to know how much network bandwidth to dedicate to QlikView.
For example, SAP might tell them 32 K o 128 K per concurrent user. Has anybody done any tests to see what is a good network bandwidth per user for the QlikView Plugin or AJAX?
Thanks for the help.
Hi Karl, did you every get an answer to this question? I have been asked the same question, usually from the IT department of an organisation....
Hi all, Same question - but about Sense. do we have any reference values about how much Qlik Sense uses bandwidth in normal usage? For example, if user does one selection in the sheet that contains 4-6 objects, how much data will be transferred between end user device and Sense server.
Thanks in advance,
Assuming the question is re network traffic from web browser to QlikView Web Server then the answer is [hopefully] not very much, but it will be bursty. On initially opening a qvw you'll get a surge as the initial html [/xml] transmits to paint the screen. Not much for a nice clean layout, loads if stuffed with hi res graphics. Same when navigating between tabs. Not too much when making selections, unless that causes a hi res graphic to be transmitted. Nothing if the user is just contemplating the dashboard or gone to make a coffee.
To give a precise figure is a bit like estimating the length of a piece of elastic being played with in a dark room. But one could guess at maybe 10 to 100 Kb/sec. But I would not wager money on that.
..... but a damn sight less than somebody watching cat videos on YouTube.
It would be great to give some average numbers. For example using some of our demos from demo site as an example.
- Opening a document = xxx
- One selection = yyy
- Changing a sheet = zzz
This way we could estimate something. Thanks in advance,
