very slow work
« on: January 28, 2015, 12:40:22 PM »
i have setup roundcube and have few month of nice work with it, but after some moves (i don't know which cause problem: adding 2 hdd, changing self-signed certificate in Apache, something else? ) it became veeeeryyyyy sssllllloooooowwwwww and i
completely can't understand what part of Apache + dovecot + exim + mysql + r-mail is a source of a problem.

slow work means i have to wait ~5-10sec when changing folder in mailbox, or trying to view another message. all that time i saw "loading" in right bottom corner

- exim and dovecot setuped on separate server (mail-server)
- i also have squrrelmail on this server (web-server) it works OK, it doesn’t use MySQL, it also DO use dovecot IMAP server
- i have other web-sites on "web-server" they work quiet OK, they DO use MySQL
- problem is still actual no mater how many letters are in mailbox
- when attaching some big ~1Mb file to email i should wait more time to redraw web-page

I can't find any help for myself viewing logs
i've upgrade 1.02 to 1.1 but it obviousy doesn't change anything

Enable imap logging, and check the timestamps to see if the mail server is the problem.
