Thanks, for the INFO I was going to mounted with translation on, however I
did FTP'd in binary when I was testing it.
Do you think if I did the gzip under uss will be faster... another word
gzip + ftp would be fater then just FTP the data without compress?

Been there! By your comment, I gather that z/Linux is running on an IFL
and not sharing CPU resources with your z/OS system. Well, a Hipersocket
connection between z/Linux and z/OS is likely to be very fast, if you
decide to NFS mount and do the gzip on z/Linux. Or even via an OSA
connection. But if z/OS and z/Linux are on separate mainframes, then the
NFS mount gains you nothing in terms of file transfer speed. Well,
unless the z/OS and z/Linux are one a faster backbone than the z/OS and
UNIX systems, of course.
I have, in the past, done an NFS mount between z/Linux and z/OS. But I
was using z/Linux as the server, not z/OS. The reason is because it was
easier for me to configure a z/Linux NFS server. Also, when I mounted
the NFS share on z/OS, I could tell the z/OS NFS client to do the
EBCDIC<->ASCII translation for me. I could still use the z/Linux
subdirectory (NFS share) in JCL via the PATH= just as I could a "native"
z/OS UNIX subdirectory. In fact, I mounted the exact same NFS share on
z/OS at two different mount points. One mount point was for BINARY mode
(no translation) and the other was for XLAT mode (automatic IBM-1047
to/from ISO8859-1).
