From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.3) Gecko/20040803 Description of problem: While using cups-lpd with about 7500 printqueues printing a small document takes very long time and its impossible to print more than 30 jobs per minute. While printing directly to cups via ipp or http there�s no problem handling thousands of printqueues with an acceptable performance. I found out that cups-lpd is polling the whole printqueues via the lo interface from the cupsd (with 7500 printqueues its about 14MB traffic on the lo interface for each printjob) before selecting the right one and send the job to it. This behaviour is very bad and slows down systems with many printqueues dramatically. Version-Release number of selected component (if applicable): cups-1.1.17-13.3.12 How reproducible: Always Steps to Reproduce: 1.set up 7000 print queues 2.print a small document via lpd 3.see what happens on lo and how long it takes Actual Results: The cups-lpd acts very slow and catches nearly all systemressources. Expected Results: It should send out small printjobs very quick. Additional info:
