      Configure pigz for Faster gzip Compression
    </h3>

    <p className="mb-4">
      This optimization configures <strong>pigz</strong> as a faster replacement for gzip compression. 
      Pigz is a parallel implementation of gzip that utilizes multiple CPU cores, 
      significantly improving compression speed on modern systems.
    </p>

    <p className="mb-4"><strong>Why use pigz instead of gzip?</strong></p>
    <ul className="list-disc pl-5 mb-4">
      <li><strong>Parallel processing:</strong> Uses all available CPU cores for faster compression.</li>
      <li><strong>Faster vzdump backups:</strong> When used with Proxmox's vzdump, it reduces backup times.</li>
      <li><strong>Drop-in replacement for gzip:</strong> It works exactly like gzip but is much more efficient.</li>
    </ul>

    <p className="mb-4">The following steps are performed:</p>
    <ul className="list-disc pl-5 mb-4">
      <li>Enables pigz in the vzdump configuration for faster backups.</li>
      <li>Installs the pigz package if not already installed.</li>
      <li>Creates a pigz wrapper script to replace the standard gzip command.</li>
      <li>Replaces the system gzip command with the pigz wrapper.</li>
    </ul>

    <p className="mb-4">
      <strong>Note:</strong> This optimization can significantly speed up compression tasks, especially on systems 
      with multiple CPU cores.
    </p>

    <p className="text-lg mb-2">This adjustment automates the following commands:</p>

    <CopyableCode
      code={`
    # Enable pigz in vzdump configuration
    sed -i "s/#pigz:.*/pigz: 1/" /etc/vzdump.conf

    # Install pigz
    apt-get -y install pigz

    # Create pigz wrapper script
    cat <<EOF > /bin/pigzwrapper
    #!/bin/sh
    PATH=/bin:\$PATH
    GZIP="-1"
    exec /usr/bin/pigz "\$@"
    EOF
    chmod +x /bin/pigzwrapper

    # Replace gzip with pigz wrapper
    mv -f /bin/gzip /bin/gzip.original
    cp -f /bin/pigzwrapper /bin/gzip
    chmod +x /bin/gzip
      `}
    />

    <h4 className="text-lg font-semibold mt-6">How to Use pigz</h4>
    <p className="mb-4">
      Pigz works the same way as gzip but compresses files much faster by using multiple CPU cores.
      Here’s how you can test its performance:
    </p>

    <CopyableCode
      code={`
    # Compress a file with gzip
    time gzip largefile.img

    # Compress a file with pigz (parallel gzip)
    time pigz largefile.img
      `}
    />

    <p className="mb-4">
      The output will show that pigz completes the compression significantly faster than gzip.
      To check the number of CPU cores pigz is using, run:
    </p>

    <CopyableCode
      code={`
    pigz -p $(nproc) largefile.img
      `}
    />

    <h4 className="text-lg font-semibold mt-6">Verifying pigz Replacement</h4>
    <p className="mb-4">
      After replacing gzip with pigz, you can confirm that the system is using pigz instead of gzip:
    </p>

    <CopyableCode
      code={`
    which gzip
    ls -l /bin/gzip
      `}
    />

    <p className="mb-4">
      The output should show that <code>/bin/gzip</code> is now linked to the pigz wrapper.
    </p>

    <p className="mt-4">
      By enabling pigz, compression-heavy tasks like vzdump backups and log archiving 
      will run much faster, leveraging multi-core processing.
