Performance regression in ThrottleAccumulator #14368

Open OlegMazurov opened 2 months ago

OlegMazurov commented 2 months ago

Description

Calling getAutoAssociationsCount() from ThrottleAccumulator.shouldThrottleTxn() (introduced by #13909) causes a severe performance regression due to #10998. Adding disk operations to a critical section creates contention between netty threads and reduces TPS.

Steps to reproduce

Run NftTransferLoadTest in single-node mode.
