From 17a6b07e0839df130ea3d4b9be4cc9a8c3ce6c8a Mon Sep 17 00:00:00 2001 From: Alexander Motin Date: Tue, 26 Dec 2023 19:36:34 -0500 Subject: [PATCH] iichid(4): Switch taskqueue to "fast" While "fast" taskqueue may be more expensive due to spinlock use, when used mainly for timeout tasks it allows to avoid extra context switches to and from callout thread, that is even more expensive.
