[Samba] samba 3.6.9-164 - is "kernel oplocks = no" option viable on purely Samba shared FS?

[Karel Lang AFD]

Hi,
anyone tried to speed up samba file transfer over the network by turning 
off the kernel opportunity locking - the so called:
"kernel oplocks = no"?

2 questions:

1.
In scenario, where you have purely data storage filesystem (no apps, 
databases anything), shared only over Samba and accessed only by windows 
client workstations - would it be OK to use the "kernel oplocks = no" 
option?

2.
is the "kernel oplocks = no" still Global option??
it used to be a global option, but i read somewhere that devs wanted to 
code it as 'Share' option - which would be great for testing ..
I can't find any 'fresh' info on it - anyone can confirm this?


thank you
