Iteration Group vs For Each Function in TIBCO BW

• A potential misuse of iteration group is to put an iteration group around a mapping activity, as shown in Figure below. This will decrease the performance if iteration count is  more.
• It is possible to iterate through the data using an xsl:for-each or xsl:for-each-group statement instead of using a group around a Mapper activity.
• These functions obviously does not apply if multiple activities must be executed for each iteration.
• If this is not the case it is much more efficient to use a single mapping activity utilizing the for-each function.
