Speed issue with FeatureMerger in FME 2014

Hi,

 

 

We recently have installed FME 2014 32bit on Windows7 64bit with 8gb RAM. We re-created a workbench to try the new FeatureMerger transformer.

 

 

The translation took a lot longer (9h vs 2.5h). The workbench is very simple, and consists of  few FeatureMerger. However, the dataset is very large (around 10 millions features points).

 

 

Our first test was to try the FeatureMerger without the Supplier First option just to compare results with the same settings of the FeatureMerger in FME 2013. Then we tested with the Supplier First correctly setted, but the translation took 9h also.

 

 

Does anybody has encountered a speed issue with the new FeatureMerger transformer in FME 2014 32bit?

 

 

Thank you for your feedback.

Hi,

 

 

the FeatureMerger is very versatile and incredibly easy to use, but unfortunately not always the most efficient solution.

 

 

For large datasets (and particularly if you have several chained FeatureMergers), I recommend also testing with the InlineQuerier instead. For some scenarios it can be an order of magnitude faster.

Hi David,

 

 

You are right about the InlineQuerier, but I wonder why the new version of FeatureMerger in FME 2014 is less efficient than the FeatureMerger in FME 2013.
