The current limit for fd-mem-pool is 1024, if there are more than 1024 fd's open, then the perf may be affected.<br></div><div>Also, the unix socket used while glfs_set_volfile_server() is only for Vol file, i.e. only for the connection btw Client and glusterd (management deamon). Hence, you may not see the IO performance increase, the patch <a href="http://review.gluster.org/#/c/12709/">http://review.gluster.org/#/c/12709/</a> introduces unix socket domain for IO path. This is what you may be interested in i guess.<br></div><div><br></div><div>Regards,<br></div><div>Poornima<br></div><div><br></div><hr id="zwchr"><blockquote style="border-left:2px solid #1010FF;margin-left:5px;padding-left:5px;color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;" data-mce-style="border-left: 2px solid #1010FF; margin-left: 5px; padding-left: 5px; color: #000; font-weight: normal; font-style: normal; text-decoration: none; font-family: Helvetica,Arial,sans-serif; font-size: 12pt;"><b>From: </b>"Ankireddypalle Reddy" <areddy@commvault.com><br><b>To: </b>gluster-users@gluster.org<br><b>Sent: </b>Tuesday, May 24, 2016 9:16:31 PM<br><b>Subject: </b>Re: [Gluster-users] libgfapi using unix domain sockets<br><div><br></div><style><!--
