ID: 40384 Comment by: sega01 at go-beyond dot org Reported By: jaspersl at xs4all dot nl Status: No Feedback Bug Type: IMAP related Operating System: Debian Linux (sid) PHP Version: 5CVS-2007-02-07 (CVS) New Comment:
I had this problem in Zenserver a while back, so I split the php package into a larger and faster, and a smaller and lighter one. I think it was on 5.2.x. I hadn't tested it in ages, but did note that with IMAP or not on 5.3.1, I had no regression in Drupal page loading times. Unless the regression is there whether it's enabled or not ;-). This might be fixed, but I definitely had the same issue. Thanks for reporting this. --Teran Previous Comments: ------------------------------------------------------------------------ [2007-02-15 01:00:01] php-bugs at lists dot php dot net No feedback was provided for this bug for over a week, so it is being suspended automatically.

The Zend/bech.php doesn't seem to doing anything with the c-client. If it takes time to _initialize_ it, it wouldn't account for the fact that the fibo() takes twice as long. ------------------------------------------------------------------------ [2007-02-07 10:51:45] tony2...@php.net It means that c-client initialization takes some time. We can't fix c-client, though. ------------------------------------------------------------------------ [2007-02-07 10:46:48] jaspersl at xs4all dot nl Description: ------------ When compiling with --with-imap (implies --with-imap-ssl and --with-kerberos because of Debian c-client) in PHP5.2.1RC3 and up (including latest CVS snap) the Zend/bench.php takes 23 seconds to complete. If --with-imap --with-imap-ssl are omitted , the bench.php takes 13 seconds. Using --with-kerberos or not has no performance impact. Other PHP versions (5.1.6, 5.2.0) take also around 13 seconds to complete. The benchmark is executed like this: sapi/cli/php -n -f Zend/bech.php I can give strace/gdb output on request.
