RE: [Dbmail] Imapd is slow as hell
I haven't even indexed my database, and with about 100 users, it's works fine. I notice no slowing at all, and most of my users use SquirrelMail to interface via IMAP, so I would think that would aggrevate the problem. I'm running Redhat 7.2, postfix, dbmail (cvs as of last week), mysql 4.0.2 on a 900 mhz pentiumIII with 256 megs -o- ram. (along with apache, and proftpd for the clients) It's all running smooth. -Micah > My imap is working fine but pop3 is very slow, I have ask a few > times on the list but apparently nobody is interested :( > > Ming-Wei > > -Original Message- > From: John Wall [mailto:[EMAIL PROTECTED] > Sent: Monday, August 26, 2002 9:24 AM > To: dbmail@dbmail.org > Subject: [Dbmail] Imapd is slow as hell > > > Imapd is slow as hell. > > pop3d is fast when i press "send and recive" but on my imapd account it > takes up to a minute before it tryes to login.

RE: [Dbmail] Imapd is slow as hell
I set up dbmail with mysql (innodb) on a small machine (pII 366, 128 MB RAM). Then I created 1 user and send a mail of 6MB, when trying to retrieve the mail with pop3 it is much slower then imap (+/- 10 min instead of +/- 30 sec). I don't think indexing the db would help, and I can't think anything else then that the pop3d is slower then imapd. Oh BTW the pop3d uses a lot of CPU (above 96%) and imapd a lot less (few %) I appreciate you asked xming -Original Message- From: Eelco van Beek - IC&S [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 27, 2002 10:57 AM To: dbmail@dbmail.org Subject: Re: [Dbmail] Imapd is slow as hell What is wrong with the speed of pop3?

I am using both IMAP and POP3. I have about 1000 users and my dbmail system is very fast. I have no problems downloading 100 emails at a time in mere seconds. This is with amavisd-new/sophie/spamassasin/razor. I think there is something very messed up with you system. I would try installing new network cards, or checking other settings on your system.

RE: [Dbmail] Imapd is slow as hell
Well, as I said, I tried it on 2 different newly installed platforms (one intel and one sparc) in two different networks with 2 different ip addresses. So the problem is really the pop3d on my system, 'cause imapd is fast as hell and pop3d is slow as hell and it is using more the 96% of the cpu (one mail, one user, so it's not the db neither). euh, using more then 96% of the cpu has nothing to do with the network, please, please, please Still thanks for the reply Ming-Wei -Original Message- From: Bret Baptist [mailto:[EMAIL PROTECTED] Sent: Thursday, September 05, 2002 6:03 PM To: dbmail@dbmail.org Subject: Re: [Dbmail] Imapd is slow as hell I am using both IMAP and POP3.

RE: [Dbmail] Imapd is slow as hell
Hi, We have noticed that and make some tests with several Webmail and mail clients as Netscape, Outlook, vs courier-imap with the same mail clients. First conclusions the PHPs' webmails are very slow except Squirrelmail because it use its own imap libraries instead of PHP-IMAP. But it's true Courier-IMAP it's much faster than dbmail-imap, we have add the mysql indexes as explained in this list, tuned the mysql config and got some improvements but never too fast as courier-imap. Then we have put the trace_level to 5 and make the same tests and we have noticed that to get each mail header dbmail-imap need 4 or 5 queries and in my opinion I think that it should be possible to get the same think with only one or two: By use a "SELECT * FROM messages" instead "SELECT field-1, field-2..." and/or change the table structure to put the mail header on "messages" whith the from:, to:, subject:, field and perhaps the body too, or just the body on messageblks. DBmail is the right way to make an isp mail solution with a lot of capabilities as CRM, etc, but we have to improve its speed and discuss to find the best way to do.

RE: [Dbmail] Imapd is slow as hell
Just a note, on your query comments, although I'm not arguing with your basic point, it's always been my understanding that SELECT statements that use '*' instead of stating field names are slower. If you don't specify the field names the database has to spend time figuring out what they are, but if you name them all it has to do it error if it can't find the name. In practice I've noticed it to be only marginally faster to explicitly name the fields rather than use the '*' wildcard. Not really noticeable unless you're doing tons of SELECT statements. Back to the point of your mail though: Is it faster to make one big conglomerate SQL statement that takes the database longer to parse? If it's the difference between one connection, and two, I doubt it, but the more you slim things down the better. That's for sure. I hate Mondays. -Micah At 03:26 AM 9/24/2002 +0200, you wrote: Hi, We have noticed that and make some tests with several Webmail and mail clients as Netscape, Outlook, vs courier-imap with the same mail clients.

Probably depends on the implementation. But if you're looking for a speed up there, you're probably barking up the wrong tree. You're better off trying to optimize away a call to the database. Any decent database will already have the column descriptions cached anyway. But even worse, select * can be a maintence nightmare. Unless your program is getting back the rows as name value pairs and picking through what gets sent back, you want to be specifying the columns and the order that they are to be sent back, not asking for everything and assuming that the order and number of the fields is what you think might be there.

Re: [Dbmail] Imapd is slow as hell
Why use messageblks? Well, for one reason, mysql has a limit on the record size so a split-up is necessary anyway.

Re: [Dbmail] Imapd is slow as hell
The basic layout for dbmail was based upon pop3 but we are interested in better schemes for imap. One of the main goals right now is to have the fastest imap server around. Better table layouts would mean a great improvement; just don't know how much time will be involved in implementing those. Things to do right now in my opinion are to fix annoying bugs and update the package with the several patches we have to release a STABLE 1.0 version asap. Right after that we can start playing with the table layouts and imap server logic to maximize speed for a 2.0 imap update.

Sure, we have already talked about that one week ago, in the bug fix list can you add the "&" character un the mailbox name to permit the UTF code, and permit dbmail to accept ISO-8859-1 charset for search functions, at this time we got an error message with Squirrelmail "unsupported character set". >Right after that we can start playing with the table layouts and imap >server logic to maximize speed for a 2.0 imap update. I will try to work on the imap speed improvements and will tell you if we got good results. Thanks for your work and your attention. Sam.

Re: [Dbmail] Imapd is slow as hell
Honestly I don't think using "select " or "select *" is a big speed difference - it's more like the ultimate fine tuning. I think dramatic results can be achieved by developing a table layout/imap logic that minimizes the number of queries and the amount of parsing done by the imap server.

Re: [Dbmail] Imapd is slow as hell
Parsing is definitely the issue. I wrote a very simple Python application to parse headers in my dbmail inbox - a run against 50 messages takes about 4 seconds on a very fast box, using standard Python libraries. The question is, what's more important - message insertion or subsequent processing. My vote is that subsequent processing (each access by a web mail, pop or IMAP client) is more important since they are 1 plus n accesses to the data, whereas insertion is a one time thing. In the short term a web mail client could use the 'seen' flag - parse the messages and write to its own tables to contain the header fields of interest, but, would be nice to see dbmail 2.0 do this on message insertion. Then watch imap fly! At 07:14 PM 9/24/2002 +0200, you wrote: Honestly I don't think using "select " or "select *" is a big speed difference - it's more like the ultimate fine tuning.

One annoying bug I've notices is the mis-match between the status and flag_read fields. When you use POP and keep messages on server, all the messages are set to be read by setting status to 02. However, Imap only seems to look at the flag_read field, which is not updated by the POP session. Suggest either syncing the two fields, or at least getting rid of flag_read. /Mark
