Slow Calendar performance

[miskolczi.peter]

SmartGWT (SmartClient Version: v8.3p_2013-05-10/PowerEdition Deployment (built 2013-05-10))

IE9

We are displaying events come from other systems. In weekly view adding 150 events takes 7+ seconds (just the line below).

calendar.setData(calendarEvents);

Expected (and acceptable) response time would be about 1-2 seconds.

Is this a known performance issue?

When could it be accelerated/fixed?

Please advise if you have any idea for quicker calendar. Thanks.

(Also we would like to display even more event for a week.)

There's always room to optimize. We can't tell whether the performance you're experiencing is what you'd expect without seeing all the code involved (and also knowing the skin).

If you ultimately find that the component is too slow for your intended usage, you can actually ask us to spend some time on optimization via the Feature Sponsorship program - sometimes there are gains that can be made with no API change (for example, tuning for your use case by skipping code that involves features you aren't using), other times, we can propose new APIs (such as a mode that uses simplified widgets for rendering events).
