PDFCreator fastest options

1- Hi, i m using your software for an automated generation of pdf on my windows 2k3 server, and it takes about 4 to 5 seconds for each pdf. I would like to know if there is any options i could able/disable that would speed up the process (compression, optimize, resolution...)

2- Also, i have to kill and restart the PDFCreator process for each generation, in c#. Is there a way to attach my instance to the already existing PDFCreator process, so that i can have 1 process for my entire automation?
