Hi,
If you are using IIS7, you can limit the max CPU usage per application pool:

If you're hosting online do you have a dedicated server? If not, most
of the shared ASP.NET hosting plans are **not** made to support high
loads. From what I've seen, this can be put anywhere from 100-250
accounts on a single VM.

If you do have a dedicated server, is it optimzed to handle large
loads? Here's one reference:
http://msdn.microsoft.com/en-us/library/ff647786.aspx
Also, have you tested any other web services not using iTextSharp on
the same server that are handling that kind of load?
You're also probably not going to get much help unless you post a
short, stand-alone example or code snippet to show everyone what
you're doing...
