<div dir="ltr">Hi,<div><br></div><div>As many of you know, gluster suffers from pretty bad performance issues when there are lots of files. One way to at least attempt to improve performance is setting cluster.readdir-optimize to on.</div><div><br></div><div>However, based on my recent tests (using Gluster 3.13.2), as well as tests of many others (like <a href="http://lists.gluster.org/pipermail/gluster-devel/2016-November/051417.html">http://lists.gluster.org/pipermail/gluster-devel/2016-November/051417.html</a>), there's a bug that frequently makes the listings of entire dirs disappear. Though the data is still there, it's a very scary bug for production systems which may think all data is gone.</div><div><br></div><div>I know Gluster 4 was recently released, but it makes no mention of cluster.readdir-optimize in the notes.</div><div><br></div><div>What's the status of diagnosing this bug and fixing it? We're experiencing major performance issues with gluster in production, and I'd love to do everything possible to get them resolved.</div><div><br></div><div>Thank you.</div><div><div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><br>Sincerely,<br>Artem<br><br>--<br>Founder, <a href="http://www.androidpolice.com" target="_blank">Android Police</a>, <a href="http://www.apkmirror.com/" style="font-size:12.8px" target="_blank">APK Mirror</a><span style="font-size:12.8px">, Illogical Robot LLC</span></div><div dir="ltr"><a href="http://beerpla.net/" target="_blank">beerpla.net</a> | <a href="https://plus.google.com/+ArtemRussakovskii" target="_blank">+ArtemRussakovskii</a> | <a href="http://twitter.com/ArtemR" target="_blank">@ArtemR</a><br></div></div></div></div></div></div></div></div></div></div></div>
