Dear All,

I am benchmarking NFS and GlusterFS  . I running Iozone in multi thread mode
.from  the test conclued that GlusterFS performs better then NFS in single
server and single client  at file size 100MB. Any commant and Idea . Is  it
correct? .Here I am using file size 100MB and 128 KB record size .In 100 MB
file size GlusterFS performs better then NFS . but when I am testing 128 KB
file size and 4KB record size ,in this case NFS performs better then
GlusterFS .what is the reson for that?  GlusterFS will perform better only
in case of   large file size ?
