[imp] very slow printing

[Jan Schneider]

Zitat von Bernd Wolf <bernd.wolf at csw-wolf.de>:

> Hello,
>
> if I use the print-icon of mails, the process waits 10-40s before  
> getting the choose-printer dialog.
>
>
> I'm using Horde Groupware Webmail Edition 5.1.2 on CentOS 6.2,  
> installed at a local server, accessing Cyrus-Imap.
> Everything looks ok, no known problems.
>
> Other clients (Thunderbird) doesn't show any performance problems.
>
> If horde-server accesses local cyrus-imap, it's about 10-20s waiting  
> - without any load, only a testsystem, 1 user.
>
> Tried with MS-Windows IE, but mostly using Firefox from linux desktop.
>
> What's to be seen:
> - download of email using the icon works very well
> - print of email using the print-icon: long waiting
>   - checked network/server-load: server's cpu-load goes to 100%  
> during wait, network traffic is at the beginning
>     and at the end very shortly
> - print from browser's STRG+P works very well, but not very nicely formatted
> - mail server load: no visible time to wait, no problems in logs or  
> with performance
>
>
> Any idea about this?

A quick check at an xdebug profiling shows that all this extra time is  
spent inside the Sabberworm CSS parser.
