Hello, I run the bulk-update challenge: **esrally --pipeline=benchmark-only --track=eventdata --track-repository=eventdata --challenge=bulk-update --track-params=bulk\_size:10000,bulk\_indexing\_clients:64 --target-hosts=10.145.14.241:9200 --client-options="timeout:240" --kill-running-processes** we are quite happy with the results however tests run 7 days. Data is stored in elastic. Questions: 1. having data populated into elastic, will it be possible to reduce the time execution for 6 hours or 1 day and got the performance of the last day load. I know to control the number of cycles in bulk-update.json 1. from the execution It shows the 1 phase is most operations are writes but the majority of the load comes from the reads. I tried to find how it works in the code but it is not clear to me where the switch from write to read is happening. [https://github.com/elastic/rally-eventdata-track/blob/master/eventdata/parameter\_sources/elasticlogs\_bulk\_source.py](https://github.com/elastic/rally-eventdata-track/blob/master/eventdata/parameter_sources/elasticlogs_bulk_source.py) 1. Also it looks like the rally client executions are adapted based on response time. In my case rally machine has 64 CPUs and utilization up to 10%, and it is around 130 MB per / second how can I accelerate thruput from rally client ![image](https://us1.discourse-cdn.com/elastic/original/3X/5/d/5d4c7d31aa278063d36637dce7c7c6fd42148a09.png) ---

Can you guys please answer the question. It is required knowledge of some framework internals and it would really speed up our research. Thanks in advance. ---
