Dear Till, Thanks for your investigation of this problem. Below are the information we found maybe helpful for the investigation: As we said before:"The phenomenon that print jobs slower in 16.04 is more obvious when printing many jobs in the same time." We figure out that the interval time of one print job to the next print job is huge when print many jobs in the same time. And the error_log files shows that the step below takes time , this step is only exist in 16.04: "Expiring subscriptions..."
---------------- Attach file description: File 1: error_log.1-16.04-orca-rpdl-20181113_Job284_290: error_log of Job284 to Job 290 is the consecutive printing 7 jobs on 16.04 in the same time. File 2:error_log.2-14.04-orca-rpdl-20181114_Job327_332 : error_log of Job327 to Job 332 is the consecutive printing 7 jobs on 14.04 in the same time. ----------- By the way, we did the ghostscript investigation of you advice, but we didn't found it cause the slowdown problem.
