    Looks like you have your answer, but there are a crazy number of possible issues.\n
    \n
    The biggest cause is misreading the performance specs.\n
    \n
    A partial list of other options:  \n
    Mechanical drives store data in rings. Outer rings have higher speeds than inner due to constant angular velocity.  \n
    Seeks cost a lot of throuput on mechanical drives.  \n
    Oversubscribed drive cables.  \n
    HBA issues.  \n
    PCIe data path conflicts  \n
    Slow RAM  \n
    RAM full or busy  \n
    Extra cpy within RAM  \n
    NUMA path issues (of drives are connected to different NUMA nodes. Not an issue on desktops.)  \n
    CPU too busy  \n
    Transfer software doing extra things  \n
    File system doing extra.  \n
    RAID doing extra.  \n
    NIC on a different NUMA node than HBA (can be good or bad).  \n
    NIC sharing the data path in a conflicting way.\n
    \n
    There are others. Start with checking theoretical performance from data sheets.\n
    \n
    Also, details matter, and I don’t have enough of them to guess.

  +description: """
    From Wikipedia, the free encyclopedia\n
    \n
    Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
    \n
    Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
