TWX 9.6.1 Grid Widget Causing Massive Lag in Mashup Design

[JO_9930585]

The Grid widget seems to be causing a lot of issues when editing mashups. Has this been reported before? It lags the systems and causes my computer to use a lot of resources. It's bad enough that developing is very difficult. I cannot even bind things because it freezes for 20 seconds or so.

Edit** 9.6.2

Hi @JO_9930585

Does your mashup only contain a single Grid widget (+ few other widgets) or filled with many widgets and services?

A complicated mashup with many contents might impact the performance.

Try use contained mashups, menu or navigation function to modularize your mashup or break a complicated mashup into multiple mashups.

And is this issue always reproducible? Do other developers in your company experience the same?

Try working on the mashup at another time and try using another client computer.

Also check if your ThingWorx server is busy processing other tasks (like subscriptions, properties updates, concurrent mashup accessing requests etc) that drained the server resources (memory, CPU for example)

This occurs in any mashup with a grid, but may not be limited to this. These mashups were migrated from 9.0 and 9.3 TWX. It could be a simple mashup or a complicated one, it seems to not matter. There are hundreds of mashups that cause this issue. This issue exists on my colleagues computer as well. The issue exists when I run TWX on a different server via my laptop. The issue never existed before the upgrade to 9.6. This issue is not consistent, but mostly reproduceable. The TWX server is totally fine. It seems to be causing the local computers to use a lot of resources and not the TWX server. This might require a PTC case, but I thought I would check to see if anyone has had this issue first.

UPDATE** 

This is also happening with mashups that have a collection widget. I created a brand new responsive mashup with nothing except an unbound collection widget. The mashup lags as soon as you click the widget. It isn't nearly as bad as the Grid though.

Hi @JO_9930585 

Yes, it seems to be a sophisticated issue that requires more information to understand the issue and find out the root cause.

It'd be better for you to report this issue via a support case.

Best,

Hi @JO_9930585,

Has there been any update on this issue?

If you have opened a support case for this, could you please share the case No.?

Best,
