What does supporting CAP_LARGE_READX capability buy? I'm looking at ways to
samba performance, and was wondering if this would help. I understand that
this will only help in
case of clients speaking NT LM 0.12 dialect and only while reading large
files from server (using
The cifs spec says that:
"If CAP_LARGE_READX was indicated by the server in the negotiate protocol
the request's MaxCount field may exceed the negotiated buffer size if Fid
refers to a disk
file. The server may arbitrarily elect to return fewer than MaxCount bytes
in response. "
Does this mean that a client would ask to read more bytes (per each
read_and_x request) if this
capability is supported by samba server?
smbd/negprot.c has a comment:
other valid capabilities which we may support at some time...
I searched the samba & M$ cifs archives, but couldn't find any relevant
If it is worthwhile to add this capability, I can help out to the best of my
capacity in order
to explore further and possibly implement it.
