I'm after other QV developers experience of the difference in performance between o document on the desktop and the same document, using Ajax on the Qlikview server. My experience is that a document that works very quickly, with almost instant response to clicks and filters slows down significantly on the server through IE8 web browser. Instant reposes become 3 to 4 seconds, 1 second responses become 10-11 seconds. The feedback from users is that it is slower than they expected as we tend to demo using a local installation.
Our server is a few years old and we have a new one in the pipeline, but even on small documents (20,000 records, 2MB file, efficient expressions) we see a signficant loss of performance.
Anyone had a similar experience, does anyone have any advice, will a brand new server with more RAM, faster processes help?
Have tried different browsers, and the IE plugin. Plugin is slightly better, but not by much - we really need to use the Ajax zero footprint / IE browser in our organsiation due to the desktop policy that we have.
Will take a look into the hyperthreading, thank you.
One thing I failed to mention as well is that the server we are currently using is in the states, bulk of the users (and myself) are UK based - we're all on the same WAN, but coiuld the delays be down to latency on the network? I'm gathering response times from the states to see how they differ.
