good speed only with opportunistic locking

no idea?
Can I increase performace with 1 Gb RAM (now my NAS NV+ has only 256Mb)?

What else can I do for more performance when i read in my files.

thanks

I tried jumbo frames - no better speed :(
I disabled journaling - no better speed :(
forced cache writeing on - no better speed :(

the only one which increases speed 2000% is opportunistic locking on, but I have a multiuser application and can't use it.

What can I do to increase speed?

server string = FreeNAS Server
security = share
dns proxy = no
# Settings to enhance performance:
use sendfile = yes
strict locking = no
read raw = yes
write raw = yes
oplocks = yes
max xmit = 65535
deadtime = 15
getwd cache = yes
socket options = IPTOS_LOWDELAY TCP_NODELAY SO_SNDBUF=16384 SO_RCVBUF=16384
# End of performance section

are there some lines I can use to enhance performance in my NV+ ?

now i found this statments:

more RAM
256MB -> 1024MB: only 10-20% better performance

but thet I want to try in all shares:
oplocks = 0 (oplocks = no)
fake oplocks =1 (fake oplocks = yes)

because my application handles locking itself or
all users are allowed to read and write into the same file at the same moment.

Problem is: How can I integrate this options in my ReadyNAS NV+ smb.conf?

Please help me!
thanks
