Hi,

not the first issue about "executing too slow" but in different context...

My server isn't under pressure when I try to search at roundcube a keyword in "Entire message" in "All folders" and it gives me an "Server error! (error)" beside log file entries:

Mar 12 10:20:50 mail php-fpm[590299]: [WARNING] [pool inet] child 631270, script '/opt/www/roundcubemail/index.php' (request: "GET /mail/index.php?_task=mail&_action=search&_interval=&_q=keyword&_headers=text&_layout=widescreen&_filter=ALL&_scope=all&_mbox=INBOX&_remote=1&_unlock=loading1710235237989&_=1710234363157") executing too slow (11.950493 sec), logging
Mar 12 10:20:50 mail php-fpm[590299]: [NOTICE] child 631270 stopped for tracing
Mar 12 10:20:50 mail php-fpm[590299]: [NOTICE] about to trace 631270
Mar 12 10:20:50 mail php-fpm[590299]: [NOTICE] finished trace of 631270

Opened an issue here but closed.

Tried to play with some time limits (seems to be 10sec), like here:
https://forum.howtoforge.com/threads/ho … ost-394663

But it doesn't helped.

Any further hints for me?

Re: php-fpm "executing too slow" roundcube

Searching entire message inside a large mailbox could take long time, Dovecot cannot finish the search as soon as possible.

In this case you may need to implement FTS (full-text search) support in Dovecot.
iRedMail Easy integrates fts-xapian in Dovecot, you can give it a try:

Of course there're other solutions, do some research with Google. smile

Re: php-fpm "executing too slow" roundcube

Thanks, now it takes two seconds... ;-)

ubuntu 22.04 steps:

# apt install dovecot-fts-xapian xapian-tools
# mkdir -p /usr/local/libexec/dovecot/
# cp /usr/share/doc/dovecot-core/examples/decode2text.sh /usr/local/libexec/dovecot/decode2text.sh
# nano  /etc/dovecot/dovecot.conf
...
mail_plugins = (...) fts fts_xapian
...
!include conf.d/90-fts.conf
# nano /etc/dovecot/conf.d/90-fts.conf
plugin {
    fts = xapian
    fts_xapian = partial=3 full=20

    fts_autoindex = yes
    fts_enforced = yes

    fts_autoindex_exclude = \Trash

    # Index attachements
    fts_decoder = decode2text
}

service indexer-worker {
    # Increase vsz_limit to 2GB or above.
    # Or 0 if you have rather large memory usable on your server, which is preferred for performance)
    vsz_limit = 2G
    process_limit = 0
}

service decode2text {
    executable = script /usr/local/libexec/dovecot/decode2text.sh
    user = dovecot
    unix_listener decode2text {
        mode = 0666
    }
}
# systemctl restart dovecot.service
# doveadm index -A \*

(take a coffee)

# crontab -e
...
