<div style="padding-left:40px">Hi All,<br><br>We are running Round cube on top of dovecot and postfix as our email echo system. Main problem we are facing is that, roundcube loads really slow for big inboxes (~5000 emails). I found that, while it loads, imap process goes high in terms of CPU utilization(~90%). I asked it in some roundcube support group, They believe that it is related to dovecot not roundcube. Can you shed any light on this issue. Thanks in advance. <br><br>Here is $dovecot -n$ output<br><br><span style="font-family:"courier new",courier,monospace"><a href="mailto:manmatha@roundcube-internal-server-1:" target="_blank">xyz@roundcube-internal-server-1:</a>/etc/dovecot$ dovecot -n</span><br><span style="font-family:"courier new",courier,monospace"># 2.3.16 (7e2e900c1a): /etc/dovecot/dovecot.conf</span><br><span style="font-family:"courier new",courier,monospace"># Pigeonhole version 0.5.16 (09c29328)</span><br><span style="font-family:"courier new",courier,monospace"># OS: Linux 5.15.0-1024-kvm x86_64 Ubuntu 22.04.1 LTS</span><br><span style="font-family:"courier new",courier,monospace"># Hostname: roundcube-internal-server-1</span><br><span style="font-family:"courier new",courier,monospace">auth_mechanisms = plain login</span><br><span style="font-family:"courier new",courier,monospace">disable_plaintext_auth = no</span><br><span style="font-family:"courier new",courier,monospace">listen = *</span><br><span style="font-family:"courier new",courier,monospace">lock_method = dotlock</span><br><span style="font-family:"courier new",courier,monospace">mail_always_cache_fields = date.received</span><br><span style="font-family:"courier new",courier,monospace">mail_cache_min_mail_count = 5000</span><br><span style="font-family:"courier new",courier,monospace">mail_location = mbox:~/mail:INBOX=/var/mail/%u:INDEX=/var/indexes/<a href="http://isical.ac.in/%n" target="_blank">isical.ac.in/%n</a></span></div></div></blockquote><div><br></div><div></div></div><div>Yes.
