Thank you for the report. While we do continue to work on improving performance in general, potential performance improvements are not handled as bug reports. Moreover, without an example script and project file we cannot investigate whether the performance issue is caused by the complexity of the mesh, inefficient use of the operator in the script, unreasonably parameter choices or an inefficient implementation of the operator.

If this is a performance regression, meaning that a previous Blender version had significantly better performance with the same data and script, then please create a new ticket and attach all relevant information, including a minimal project file, the script and step by step instructions to reproduce the problem.
