I have the following problem, we migrated an application originally made in ignition 7.9, the response in writing, reading and animation is fast as needed but when running in igniton 8.1 the application does not respond the same, the reading and writing is slower in general.
We export tags and windows manually
I detected that in version 7.9 in the Scann Class property the Slow rate configuration is different from the common ones (if the value varies the application goes slower or faster)
In the ignition tag groups of version 8.1, this configuration is not the same.
Any suggestions on what I can do to return the response speed in version 8.1?
By any chance are you seeing any tags in this provider that did not exist before? Specifically tags that likely would exist in the System provider (like a Gateway or Client folder). There is a known issue where, depending on the 7.9 upgrade path over the years, a tag provider ID can be duplicated with the System provider. This can cause issues with Tag Groups as well.
If you see System Tags within the provider, I would recommend calling support so that they can help get the issue resolved.
Even if you don't have this issue, I would recommend calling them and attempting to work through the issue with them.
