Pentaho PDI version 5.0.1 is slower than 4.3

After updating Pentaho PDI 4.3 to 5.0.1, I noticed that my ETL process took 45 minutes longer to execute. So I ask myself if the new version is really slower than the old one ..

I compared the two kettle versions with the same transformation (a single Table Input to Ouput a Table). Same database, same table, same driver, same everything except PDI release (4.3 and 5.0.1).

Pentaho Kettle 5.0.1 Benchmark

Yes, Pentaho Kettle 5.0.1 is slower than 4.3. Sad but true, but this is not a deal breaker considering the new features that come with it.
