In the current testnet setup, we noticed a couple times when shared counter workload completely stop making progress that it affected the transaction throughout of transfer object workload. This is because the backoff in load gen considers total pending requests across all workloads before deciding to send a request. We aim to fix this behavior by adding a new mode (disjoint_mode) where different workloads run completely independently such that even if one is completely dead, the other keeps making progress as expected.
