Aggregate Throughput/IOPs results?

[Matt G.]

Hello there,

I am trying to build a benchmarking solution using elbencho for distributed storage performance testing, but the output from elbencho has me a little confused.

The tool gives: MiB/s [first] | MiB/s [last]

I gather that this refers to the first and last threads used during the test (8 threads total in this test), but how does one calculate aggregate throughput when using the tool in distributed mode (meaning multiple instances of elbencho across multiple hardware hosts in worker mode and one in manager mode all working against a large distributed storage system)?

I feel like I'm missing something.

Thank you in advance for your help!
