In general, it is highly recommended that CIDFonts used in the creation of PDF jobs should be embedded or available to Ghostscript as CIDFont resources, this ensures that the character set, and typeface style are as intended by the author.

However only the requested pages are rendered, which can still lead to savings in time.

Improving performance Ghostscript attempts to find an optimum balance between speed and memory consumption, but there are some cases in which you may get a very large speedup by telling Ghostscript to use more memory. This is probably useful only for debugging. Ghostscript’s own initialization files, fonts, and files named on the command line.

Please see the reference sections on options and devices for a more complete listing. X device parameters In addition to the device parameters recognized by all devicesGhostscript’s X driver provides parameters to adjust its performance. In addition, if the output device color model matches the output intent color model, then the destination ICC profile will be the output intent ICC profile.
