Major issue with grids in new 6.2 version

[corbit]

After the upgrade to 6.2 the NetXMS client on Windows is VERY slow. Every time a gridview is shown, it uses a lot of time to refresh the grid and adjust the column width - and it does that very often because of automatic refresh cycle and makes the client very slow.

Fortunately the issue is not the same on the web-client.

It's a know issue, we are working on that right now. Should be improved in next patch release.

Was this addressed in 6.2.1 ? if so I am still seeing the same thing. Its looks like a constant repainting of the data. I normally see it when looking at the Data Collection on a node or interfaces tab.

Thanks for the follow-up — you are right, 6.2.1 does not fully fix this.

The fix that went into 6.2.1 removed the visible flickering of the columns, but not the underlying cost. Grid views still re-measure and repack every column on each refresh cycle, and that is what you are seeing as constant repainting on the Data Collection and Interfaces tabs. On a node with many interfaces or DCIs a refresh can be triggered very often, so it never settles.

I've opened https://github.com/netxms/netxms/issues/3418 to track it. The proper fix is to repack columns only when the content actually changes shape (new columns, first data load, or when you ask for it), instead of on every refresh.

Until then you can avoid the problem by unchecking "Resize columns automatically" in the view menu of the affected view. The setting is remembered per view, and with it off the columns are no longer repacked on refresh.
