• If you want to improve performance, you could merge attribute columns into your feature class table. For more information, see About joining and relating tables.

More information

You are joining your feature layer with more than one joined table, which may potentially result in poor drawing and query performance. You can test your map or globe to see if display performance will be acceptable.

If your application warrants the use of multiple joins, you can choose to mark this warning as an exception to avoid receiving the warning next time you analyze the document. Beware that the resulting map or globe may draw more slowly.
