socket options

[Samuel C. Martinez]

Do the socket options still work with versions of samba above 1.9.16p10?  I
get error messages both on the command line and in the smb.log file that say:

Unknown socket option IPTOS_LOWDELAY
Unknown socket option TCP_NODELAY

Here is my smb.conf Global parameter entry:
socket options = IPTOS_LOWDELAY TCP_NODELAY

Do these have to be compiled into the Samba program?

If these are outdated parameters do you have any others that will replace
these?  

We are trying to compare the Intergraph NT NFS package with Samba, and so
far samba is at least 30% slower than Intergraph.  Do you have any
recommendations for improving performance on Samba using the latest versions?

Thanks in advance for any help you can give on this.
