I'm learning!Well, SMB is single-threaded.
I've been doing tests:
Code:

...and there are odd asymmetries to transmit/receive via TCP/IP.
While I was perusing some test code, I saw a few lines that seemed interesting:
Code:
root@truenas[~]# dd if=/dev/zero of=/mnt/WolfTruePool/test/test.dat bs=2048k count=10000 10000+0 records in 10000+0 records out 20971520000 bytes transferred in 3.821498 secs (5487774807 bytes/sec) root@truenas[~]# dd of=/dev/zero if=/mnt/WolfTruePool/test/test.dat bs=2048k count=10000 10000+0 records in 10000+0 records out 20971520000 bytes transferred in 0.753427 secs (27834838083 bytes/sec) root@truenas[~]# dd if=/dev/zero of=/mnt/WolfTruePool/test/test.dat bs=2048k count=10000 10000+0 records in 10000+0 records out
With all the tests I'm coding, I think I need to record all this so I don't forget.
