_Finally, I would be interested if the author tested the portable versions as 
well._

No, unfortunately we did not analyze this aspect.

> Performance Issue with Spark Runner compared with Native Spark

>                 Key: BEAM-9440
>                 URL: https://issues.apache.org/jira/browse/BEAM-9440
>             Project: Beam
>          Issue Type: Bug
>          Components: runner-spark
>            Reporter: Soumabrata Chakraborty
>            Priority: Major

> While doing a performance evaluation of Apache Beam with Spark Runner - I 
> found that even for a simple word count problem on a text file – Beam with 
> Spark runner was slower by a factor of 5 times as compared to Spark for a 
> dataset as small as 14 GB.
> You will find more details on this evaluation here - 
> [https://github.com/soumabrata-chakraborty/spark-vs-beam/blob/master/README.md]
> I also came across this analysis called _**Quantitative Impact Evaluation of 
> an Abstraction Layer for Data Stream Processing Systems_ 
> ([https://arxiv.org/pdf/1907.08302.pdf] / 
> [https://ieeexplore.ieee.org/document/8884832])
> According to it, the observation was that for most scenarios the slowdown was 
> at least a factor of 3 with the worse case being a factor of 58!
> While it is understood that an abstraction layer would come with some 
> performance cost - the current performance cost seems to be very high.
