We are intending to use wkhtmltopdf to convert html to pdf but we are concerned about the scalability of wkhtmltopdf. Does anyone have any idea how it scales? Our web app potentially could attempt to convert hundreds of thousands of (reletively complex)html so it's important for us to have some idea. Has anyone got any information on this?

You can create own pool of the wkhtmltopdf engines. I did it for a simple use case by invoking API directly instead of start process wkhtmltopdf.exe every time. The wkhtmltopdf API is not thread-safe, so it's not easy to do. Also, you should not forget about sharing a native code between AppDomains.
