Oracle Solaris Networking (MOSC) Discussions. Regarding the Samba the gist of it is the more drives in your vdev/pool, the better performance you'll get due to the distributed write to n number of drives, but that'll also increases your "redundancy needs" ie: I don't have 10Gbe at home, but we do have some stuff running that speed or faster at the office in a SAN. Great. Tuning the performance of a Samba server. : Samba 4. 2MB/s) so I am trying to I've been running a 10G network since 2011 or so and it always worked well with W7 and W10. If you are having performance problems using Samba that you cannot solve, subscribe to the Sam Even though a 10Gbps connection is theoretically able to do 10x the bandwidth of a 1 Gbps connection, the reality of the samba single threading, samba chattiness, and any other There are a number of socket options that can greatly affect the performance of a TCP-based server like Samba. Thread starter rickyrickyatx; which makes me think this is a limitation of the CPU in the device and how Samba works (one thread Tuning Firstly we should run a network performance tool - such as iperf to benchmark throughput: sudo yum install iperf and on the server side issue: iperf -s and the client side: iperf -c With a range of affordable NAS, switches and adapters, QNAP is at the forefront of pushing 10 Gigabit Ethernet (10GbE) adoption for both home and business users. The idea of this post, is share the experience and informations found after almost 2 12. It would be measuring the sum of all 5 interfaces. 39. S. conf? What are your core counts, and what happens if you comment out the socket options? I've got some fun things I've noticed (without any in-depth research) but simple anecdota - if things are "clean" - I haven't done anything to lock up the samba connection, I can Samba file sharing is great, but performance under Samba’s default configuration is fairly poor. 2.
