Dear Till, Thank you very much for taking your time to help investigate this issue and providing us a way to judge if "Ghostscript" causes the slowdown of "pdftops" even when you are so busy.
If possible, can you do us a favor on the below investigation： We found that Ricoh PS driver does not slow down very much actually, we found that the drivers which uses "pxlcolor / pxlmono" slow down obviously, so we provided error_log of Ricoh pxlcolor driver in #9. You can refer to the error_log in #9 on this page. In this log, we can see that the time interval between [Starting process "renderer"] and [Closing renderer] really slowdown obviously in Ubuntu 16.04 than in 14.04. In the interval, there is "Running command line for gs". We doubted that maybe the Ghostscript causes the slow down, but the developer of Ghostscript proved that the gs only slowdown very little time. Please refer to https://bugs.ghostscript.com/show_bug.cgi?id=700380 So, we doubted that maybe the module around Ghostscript(for example: foomatic-rip) causes the slow down. Could you have a look at the log in #9 (and later), and do some analysis when you have time? If you have further investigation result, it’s appreciated to share with us.
