How much higher? Can you check the individual dovecot processes'
CPU usage? I guess mainly director, imap-login and pop3-login.
The director code should be pretty much the same though.</div>

<div>The SSL code in login processes changed in v2.3, so I wonder
if the new code has some performance issues.</div>

<p>Just for info,</p>
<p>I have upgraded all directors ring to Dovecot 2.3 <span

same, so the increase of load during the first upgrade was
caused by CentOS 7, not by Dovecot 2.3.</span></span></p>
