https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D251052 Bug ID: 251052 Summary: SCTP traffic becomes extremely slow under load Product: Base System Version: 11.4-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Many People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: preynold.freebsd@gmail.com Given a service using SCTP, when it receives a spike in traffic, it becomes extremely slow to respond. A given block of traffic that takes seconds if spaced out in time, instead takes upwards of 15-20 minutes if received in a burst. I suspect some sub-optimal behavior when receive buffers are full, b= ut that is just a wild guess. This behavior is reproducible on both 11.4-RELEA= SE and 12.2-RELEASE. I will attach a test program. --=20 You are receiving this mail because: You are the assignee for the bug.=
