Do cursors cause poor performance?

Is there a way to return a result set in a stored procedure with out using a cursor? The Microsoft folks I work with claim that the use of cursors causes poor performance and shouldn't be used.

Performance strengths and weaknesses vary across all database products. Cursors might be slow performers in the Microsoft database engine, but work just fine on DB2 UDB for iSeries. External stored procedures can return a result set via an array, but the result set contents are passed back to the application in the same manner.
