[horde] VERY slow login...

[Wang, Yu]

The login failure with bad credential occurred several times when users reached about 100 and I did some tests and found that our IMAP was more than two year ago and it just cannot handle the heat even server is 4u4G. I don't know how did you setup the login. What page does a user see? the 'Welcome page" or their INBOX? My login to the "Welcome page" is fast (1 sec). But since I have big INBOX (around 1000 emails). Open my INBOX generally takes a while. 

Do you run many other services on that box (like web, telnet, ftp...)? I assume your IMAP is invoked by inetd. Check to see if you have limit set in your inetd config. To isolate the problem from Horde and IMAP/Other part, you can do following test:
When login failure or slowness occurs, use a different mail reader (like outlook express) to do IMAP connection to the same server. If you see failure or slowness too, it's not Horde's problem. check your IMAP and other things. Otherwise, it's Horde that needs to be tuned.

Ok, here we go.

1.  Don't know, about 11 gigs so far of storage.
2.  Old IMAP?  Can you elaborate?
3.  p3 1ghz, 3 gigs ram, UltraScsi 3 Software RAID 5.

The thing is, the page opens very quickly, and once you're IN, it's as fast as you can click.

I found 

1. Big INBOX and lots of subscribed folders can cause poor login performance. 
2. Old IMAP can cause login failure when users reach about 100.
3. Not so powerful server can be another factor.
4. I don't know:)

If your mail server or auth server (I don't know what you are using for your 
users, mysql, ldap, imap, ?) is not on your horde/imp machine, be sure to 
check that all the other mail/auth server you are connecting to are well 
defined in your dns or in your /etc/hosts file.

Otherwise, your can wait for a reverse dns call to timeout, more users there 
are, the longer it gets.
