Maximum number of filter and cmd handler pane in VLF One

Post by gyehyun.kim »

I know we can set the maximum number of open filter and command handler panes through #MaximumOpenFilterandHandlerPanes.

Here's a simple question about this.
I'd like to know what the concern to limit the number of panes is and the practical limit that can be recommended.

Thank you very much in advance.

Open handler or filter panes consume resources with their code (generated JavaScript) and in the browser’s DOM with their visual controls, so it is probably a sensible idea to control how many are open at any point in time.

An additional reason for this limitation is that allowing too many things to be open may cause end user confusion through overly crowded panels, long selection lists, etc, etc.

I don’t think there is a one-size-fits-all limit that could be recommended.

Setting a viable limit be would be a factor of the amount of generated JavaScript code in a filter or command handler, the number of and complexity of the visual controls in each command handler and filter, and of course, and possibly most importantly, the overall CPU power and memory of the device(s) the browser is being used on. For example, you would expect an Intel i7 with 32Gb of RAM to be able to handle a lot more than an iPad (say). The choice of browser might also be a factor to consider.
