Sorry for the late reply, I had some other more urgent tasks to do. I have looked into your log.
foomatic-rip was running for 5 seconds (09:09:52 - 09:09:57) and it ran this time due to the Ghostscript process it called and which by itself ran at least 4 seconds. This does not look for a very long time and if you think this is for the document which you had sent, it is a problem of Ghostscript. As foomatic-rip calls the pdftops filter of cups-filters and then pdftops calls Ghostscript for actually converting the incoming PDF to PostScript, you can let pdftops use Poppler instead of Ghostscript for this task to see whether Poppler processes the job more quickly. To switch pdftops to Poppler, use the "pdftops-renderer=pdftops" option (see README of cups-filters, /usr/share/doc/cups-filters/README.gz). If with Poppler your jobs go more quickly, report a bug on www.ghostscript.com, supplying a sample input file and the Ghostscript command line (you find it in CUPS' error_log). Before doing this please also try to run the Ghostscript command line directly on the input file from a terminal window, to check whether Ghostscript was really that slow. Also printing very many and/or big jobs in a row and observing the output of the "top" command could help. If the problem is not the slowness of Ghostscript but the "Removing document files." task afterwards taking a full minute (does this make the next job wait that minute?) report a bug on www.cups.org. Note that this delay is not caused by Ghostscript or foomatic-rip as these processes had already ended before. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1801496 Title: Printing job in 16.04 is slower than in 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1801496/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
