Configure pigz for Faster gzip Compression
</h3>
<p className="mb-4">
This optimization configures pigz as a faster replacement for gzip compression. pigz is a parallel
implementation of gzip for modern multi-processor, multi-core machines.
</p>
<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.

<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.
