sorry to hear that. For RDS-TCP, the rx side does show a noticeable
benefit with rds-stress. To an extent, this is also impacted
by the packet size, and the type of test (for our DB workloads,
we use request-response tests, and the packet size tends to
typically be 8K req, 256 byt responses), so I guess ymmv.
