From 7f199dbf0261b89afe0dc8185db4403ae0efdefa Mon Sep 17 00:00:00 2001 From: Amir Shehata Date: Thu, 5 Sep 2019 14:28:48 -0700 Subject: [PATCH] LU-12385 lnet: update opa defaults Testing reveals no significant performance improvements when using peer_credits > 32. Adjusted the default peer_credits, peer_credits_hiw and concurrent_sends to take that into account. This has the advantage of avoiding an issue observed on multiple opa sites where the qp can not be created because of large initial queue_depth. The queue depth is then reduced gradually until the qp creation succeeds.
