Hi

Batch interval is 5min. I actually managed to fix the issue by turning off
dynamic allocation and the external shuffle service.

This seems to have helped and now the scheduling delay is between 0-5ms and
processing time is about 2.8min which is lower than my batch interval.

I also noticed that enabling dynamic allocation and the external shuffle
service had a high impact on cpu usage.

Thanks
Juan
