    no(network option) tuning:
    no -o send_file duration=180000(cached send_file expiration time, default=300)
    somaxconn=8192(max listen backlog, default=1024)
    nbc_max_cache=131072(max file size for network buffer cache,default=1048576)
    nbc_pseg=20000(max file entries in private segment,default=0)
    tcp_timewait=5(ensure that TIME_WAIT is at least 60 seconds, default=1)
    Processor affinity - bind 8 Ethernet interrupts to 8 cpu's(1 interrupt to 1 cpu)
    maxpgahead=56(the maximum number of pages to be read ahead,default=28)
    maxfree=296(the number of frames on the free list at which page stealing is to stop,default=256)
    minperm=5%(the point below which the page-stealer will steal file of computational pages,default=20%)
    maxperm=95%(the point above which the page stealing algorithm steals only file page,default=80%)
    Used 1 external 7026-F/C6324 I/O drawer ( 4 adapters each ).
