The bug post was about excessive RAM usage leading to swapping. High CPU usage
shouldn't be a problem. Moreover pdftoraster takes more time than other
filters. Try using gstoraster for faster compilation.
The original issue was resolved here:-
I would recommend to clone the repo and then install it. "pdftoraster"
currently runs as a standalone executable but I believe a simple

RAM for a 4GB OS. It also takes significant time to do the job but it is way
more for your case. This will be sorted out soon in the next releases of
cups-filters which would be coming with cups package for

So actually pdftoraster takes significant time and uses significant ram while
processing. But it is using way too much in your case. This is because
pdftoraster comes with extended features. Whereas gstoraster is quite fast and
it also does not hog this much of memory. Although CPU

Can you please attach the error_log too. It is located in the var/log/cups
