Tools for testing transfer speed to an already mounted SMB?

Say I have mounted /mnt/mount_test as a samba mount and I want to test the transfer speed from my local system to that mount.

I want to know: after the mount is mounted, what transfer speeds am I getting?

I have this FIO script but I'm not sure if that properly represents transfer from my system to the SMB system?

fio --loops=5 --size=1G --directory=$TEST_DIR --stonewall --ioengine=libaio --verify=0 --direct=1 \
  --name=Seqread --bs=1m --rw=read --iodepth=64 \
  --name=Seqwrite --bs=1m --rw=write --iodepth=64 \
  --name=512Kread --bs=512k --rw=randread --iodepth=64 \
  --name=512Kwrite --bs=512k --rw=randwrite --iodepth=64 \
  --name=4kQD32read --bs=4k --rw=randread --iodepth=32 \
  --name=4kQD32write --bs=4k --rw=randwrite --iodepth=32

What I could also do is copy a file with dd like so:

time sudo dd status=progress if=/home/testuser/10GB_FILE.txt of=/mnt/mount_test/10GB_FILE.txt bs=128M

Would this properly test the speed or am I missing something?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
