Roundcube on large mailbox
« on: November 19, 2019, 02:21:08 AM »
Hello.
I have an issue: rouncube on large mailbox (289000+ messages in INBOX) not showing mail in INBOX folder. Other boxes, including my own, works fine.
My setup:
Mailboxes stored on NFS storage, perhaps this is an issue.
Debian 10 x86_64 with kernel 4.19.0-6-amd64 on a KVM virtual machine with 12 Gb RAM, host with SSD RAID10. No CPU/RAM lack issue
Roundcube 1.3.8, latest in Debian repo
Dovecot 2.3.4.1, has some NFS-related recommended config changes; indexes and volatile directory stored on local disk; fts_lucene enabled
MariaDB 10.3.18
Apache 2.4.38-3+deb10u3
PHP 7.0 (1024Mb memory limit, 50Mb max post size, 50Mb max upload size, 600 s max execution time)

How can I resolve this issue?
Thank you.

You can enable imap_debug in Roundcube to see what commands are executed and with what response time. Check if setting messages list sorting column to "None" helps.

Thanks for your reply.
Here is part of config about sorting column:
Code: [Select]
// default messages sort column. Use empty value for default server's sorting,
// or 'arrival', 'date', 'subject', 'from', 'to', 'fromto', 'size', 'cc'
$config['message_sort_col'] = '';
Set to ampty string (None?) already, this is by default, as far as I can remember.

Investigation shows that roundcube is not a problem.
Dovecot has a trouble with such huge mailbox, especially on NFS storage.
So, I will be play with dovecot setings.
Thanks for paying attention on my question.
