We make extensive use of the ghostscript in our application. Basically application provides the document transformation capability. Currently we used to invoke GS process for every transformation request that we receive, but this has a tremendous performance overhead.
To overcome this issue, we decided to convert the GS process as a server. We achieved this by making GS process start and then communicate with it using the pipes.
We invoke GS (V 8.63) with various options (example: -dPAPERSIZE, -dDEVICEWIDTHPOINTS...etc). We need to identify a way we can pass these options effectively to the ghostscript when it runs in the server mode.
Ghostscript is not an Adobe Product, it competes against Adobe's Acrobat product line. These forums are not the appropriate place to receive help with the product. I do not know of a forum which would be appropriate.
