Gatling Aggregate report Generation with big simulation files take lot of time

Gatling (Open-Source)

Hello Stephane,

With open source gatling version we are scaling and doing our load testing. Our workload is heavy and we tested with 300k transaction per second from 5 machines. The problem/worrying thing is report generation part.

Total test duration : 5 minutes
The total file size from all the machines is around 17 GB.

For report generation it took around around 30 - 40 minutes. We planned to run for more than a hour and it would be really nightmare to get the reports. Is there anyway to speed up the report generation process ?

Options I tried:
Run maven report generation only with multiple thread option (mvn -T C8 gatling:test -ro)

but this didn’t helped actually. Could you please suggest any other way to speed up the report generation process ?

Thanks,
Ram

That’s one of the things where FrontLine shines.

Hello Stephane,

I understand Frontline handles this, could you please give some approximate number for ‘Total Time taken for processing 10 gb logs file’ in frontline edition ? It would be really greater if you expose the faster report generation functionality in open source version.

Thanks,
Ram

No, FrontLine doesn’t use a log file but a completely different mechanism. Stats are computed as a stream in real time.
