anyone tried to speed up samba file transfer over the network by turning
off the kernel opportunity locking - the so called:
"kernel oplocks = no"
I've read a lot of discussion on this topic and people reported speed up
in file transfers as considerable.
Thing is, if "kernel oplocks = no" then any linux process accessing file
on the samba share for write access would respect (wouldn't know) that
samba client is writing into it, hence file corruption would happen.
But what about scenario, where you have purely data storage filesystem,
shared only over Samba and accessed only by windows client workstations
- would it be OK to use the "kernel oplocks = no" ?
i can't find it stated anywhere properly and clearly, if this is global
option (which would be bad) or 'per share' option (which would be great
for testing ...
would be glad for any piece of info,
