When having two RHEL 6 Linux servers separated by a load balancer serving Tomcat and Apache content, if the data is shared between the 2 servers via a network locally-mounted filesystem, does it matter whether this filesystem is CIFS or NFSv3?  Should I expect comparable performance from either?  Are there any pros or cons to one versus the other?

There is a wonderful benchmark estimation available from here. Most of the contents in the above link are just pictures which says it all. However, for reference sake, this is the benchmark for reading a 5 GB file.So by the looks of it, for Linux systems it is suggested to use NFS.
