<p dir="ltr">Pavel,</p>
<p dir="ltr">Thanks for sharing. I have a few comments.</p>
<p dir="ltr">1. The article only compares disk space usage and nothing else. Performance, memory footprint, maintainability etc are all left aside. If this is the only optimization criteria for you, it's fine, but usually such comparison won't work. Say, you compare two Linux distros by their installation time and find out that Gentoo is the worst of all, and any live CD based one is the best (as it doesn't require installation at all, so installation time is zero).</p>
<p dir="ltr">So, due to the fact you only have one criterion in your comparison, the conclusions you came to are also incorrect, at least from my POV. It can be something like "you can achieve disk space savings with ZFS, while with ploop there is a certain overhead" or so.</p>
<p dir="ltr">2. "due to ploop bugs" — the term bugs is obviously used incorrect here.</p>

<br>
Big thanks for your attention to my work about ZFS:<br>
<a href="https://github.com/pavel-odintsov/OpenVZ_ZFS" rel="noreferrer" target="_blank">https://github.com/pavel-odintsov/OpenVZ_ZFS</a><br>
<br>
And I would like to share with community our own ZFS tests from<br>
FastVPS Eesti OU experience (<a href="http://fastvps.ru" rel="noreferrer" target="_blank">fastvps.ru</a>).<br>
<br>
We are company with 5 year experience with OpenVZ in heavy production usage.<br>
<br>
We have used ploop, simfs and ZFS for many years together. And we<br>
operate about 1PB (yep, it's single pe-ta-by-te) of customer's data<br>
with great care.<br>
<br>
So, we could share this article:<br>
<a href="http://www.stableit.ru/2015/07/effectiveness-of-zfs-usage-for-openvz.html" rel="noreferrer" target="_blank">http://www.stableit.ru/2015/07/effectiveness-of-zfs-usage-for-openvz.html</a><br>
which shown how ZFS bit ext4 and ploop.<br>
<br>
Feedback and another tests are welcome!<br>
<br>
Cheers!<br>
<br>

Sincerely yours, Pavel Odintsov<br>
