Dan,
The slow performance appears to be due to oplocks being disabled.
You can enable oplocks using svccfg but there's a caveat - we have
been testing with oplocks disabled and I have no idea whether or
not you'll encounter problems. I'll ask for a regression cycle
with oplocks enabled but, for now, I can't provide any guarantees.
svccfg -s smb/server
svc:/network/smb/server> setprop smbd/oplock_enable=true
svc:/network/smb/server> quit
You can check the setting using:
svccfg -s smb/server listprop | grep oplock
which should produce:
smbd/oplock_enable boolean true
To update the SMB service:
svcadm restart smb/server
