Relax the TCP reassembly queue length limit to improve performance
(For tracking this fix in TrueNAS 11.2)
*Original ticket description:
See discussion on forums at
Two different reports of erratic network issues between FreeNAS and MacOS clients after upgrading to U6, observed in SMB and SCP timeouts and/or network performance dropping to zero, sometimes recovering before dropping to zero again.
Symptoms verified on MacOS 10.13.6 and 10.12.6.
Disappear after rollback to FreeNAS to 11.1-U5, everything else equal.
