[gs-devel] Performances and NOBIND parameter

[Patrick Magon]

Hello,

I'm using ghostscript to convert postscript files to pdf. As we have a lot
of documents
to convert every days, I'm trying to improve the performances by tuning some
parameters.
I have found that adding the "-dNOGC" and "-c 3000000 setvmthreshold"
parameters, I can win a couple of ms. by document.

I also found that using the "-dNOBIND" parameter I can dramatically improve
the performances (200ms instead of 400ms !!).

My problem is that I don't really know what can be the impact of this option
on the produced pdf (so far, I don't see any).
I tested with gs version 7.07: the NOBIND parameter doesn't improve much.
With version 8.15: very big gain. Unfortunately
with version 8.61 (last) I'm not able to produce the pdf file: I get the
following error:

No problem without the NOBIND option. I am really not a postscript
specialist... :( the loaded font exist.

My questions:
What can be the impact of using the NOBIND option on the generated pdf file
?
Why this option doesn't works with the latest version of ghostscript ? What
could I do about that ?
Do you have another solution to improve conversion time ?


Thank you for your help !

Patrick

PS2: I didn't find any user mailing list or forum (only dev ?)
