Glad to see python package "spotfire" is rewritten on version 2.0.0(spotfire 12.5) and sbdf read/write performance is greatly improved.
However, as far as I have tested, although spotfire.sbdf.export_data() is greatly improved and much faster than before(v10.10) when data is getting larger, spotfire.sbdf.import_data() is not faster enough, especially when data is getting larger, it may be even slower than before.
Please continue improving spotfire.sbdf.import_data().
My test result is attached.
The Spotfire package is very useful yet I did not even know about its existence until a user asked a question on the Community. I cannot find any documentation. It would be good if it were more advertised/documented.
