Disk, NFS, AFS test results

Only very stupid performace testing for different network filesystem and coparision with local disk performace

* Test on files RedHat 7.2, 7.3 RPMS distribution (relatively large files)
    cp: /home -> /afs ... 4.5GB/12min, load 2.5-3
    cp: /home -> /nfs ... 4.5GB/12min, load 3-4
    cp: /home -> /home ... 4.5GB/11min, load 3-3.5
    cp: /home -> /dev/shm ... 256MB/17s
    cp: /afs -> /dev/shm ... 256MB/40s, 256MB/8s
    cp: /nfs -> /dev/shm ... 256MB/24s, 256MB/20s
    rm: /home ... 4.5GB/21s
    rm: /afs ... 4.5GB/55s
    rm: /nfs ... 4.5GB/22s
* Test on files from documentation directory (a lot of small files)
    cp: /usr/share/doc -> /home ... 360MB/2min
    cp: /usr/share/doc -> /afs ... 360MB/5min
    cp: /usr/share/doc -> /nfs ... 360MB/3min
    cp: /usr/share/doc -> /dev/shm ... 256MB/60s
    cp: /afs -> /dev/shm ... 256MB/80s, 256MB/70s
    cp: /nfs -> /dev/shm ... 256MB/63s
    rm: /usr/share/doc ... 360MB/37s
    rm: /afs ... 360MB/60s
    rm: /nfs ... 360MB/32s
* Test start OpenOffice (first/next start)
    afs: 25/6-7
    disk: 20/6
