Bug ID: 193984
Summary: SMBFS transfer very slow and sometimes hangs
indefinitely
Product: Base System
Version: 10.0-RELEASE
Hardware: i386
OS: Any
Status: Needs Triage
Severity: Affects Many People
Priority: ---
Component: misc
Assignee: freebsd-bugs at FreeBSD.org
Reporter: jean.m.cyr at gmail.com
Server is MS Server 2012, clients are FreeBSD Web 10.0-RELEASE-p9 FreeBSD
10.0-RELEASE-p9.
Copy of large file from server does not exceed 1Mbps over wired GigE. Similar
FreeBSD 8 and Linux boxes achieve 20-30Mbps under same conditions. All NICs are
Intel and have auto-negotiated to GigE.
Hanging FreeBSD 10 permanently (requires power down, reboot command hangs) can
be reproduced as follows:
Copy three large folders recursively in parallel. ie:
cp -R /mnt/SRVR2012/a ~/a &
cp -R /mnt/SRVR2012/b ~/b &
cp -R /mnt/SRVR2012/c ~/c &
Mount done using standard mount_smbfs command.
