Title: Roundcube 1.3.7 Performance issue
Post by: Su Ak on November 29, 2018, 02:11:51 AM
Hi,

I have an issue with Roundcube webmail that most of time it takes about 10 seconds to open a folder, searching for a mail or sending new mail.
I enabled IMAP debug mode with level 8 but nothing is found. I think this delay is not coming from IMAP server because I login with different clients (Thunderbird and outlook) and everything is OK.

Following are our system environment:

- Both mail server and roundcube web server installed on separated centos 7 servers
- The mail server use Postfix and Dovecot
- Roundcube webmail Configuration info:
PHP 7.2
MySQL/MariaDB database
nginx/1.12.2
- Used these roundcube plugins: managesieve, newmail_notifier
- Currently only five users (with small number of folders) are login into the webmail but this number will be increased up to 1500 users..

any ideas to increase the performance speed?

Enable imap_debug and post the log.

It looks like the actual communication with the imap server is fast so if I had to guess there is some sort networking problem either between your location and the Roundcube server or between the Roundcube server and the Mail server.
