Several features were added to Forefront Protection 2010 for SharePoint (FPSP) to enhance its performance capabilities. The main areas that were addressed were improving document uploads and increasing the general system performance when FPSP is added to your SharePoint environment.
In comparing the performance of FPSP against the previous version of the product, Forefront Security for SharePoint (FSSP), it was determined that there is an 81% “out of the box” improvement in uploading documents. In addition, it was estimated that adding FPSP results in an overall system performance overhead of approximately 21%.
User Model: Typically, SharePoint users navigate to FPSP for a variety of activities. During their interaction with FPSP, 15% of the time they are downloading documents, and 5% of the time they are uploading documents. The overall upload/download rate is 2 requests per second.
Note: This model was selected to provide a near worse-case scenario on usage that generates conservative estimates on the overall impact of adding protection to your SharePoint environment.
Content: All tests performed used a pre-chosen message mix that contained various types of Office documents, of which there was an even distribution of Office 2003 and Office 2007 data. Each file type used was comprised of varying degrees of size and complexity.
Scenarios: The following scenarios were tested:
Measurements/Metrics: The measurements/metrics were as follows:
The following table shows the test results when using the scenarios and metrics described above.

FPSP vs. FSSP Improvement (OOB)
Conclusion: As previously stated, based on this testing, there is an 81% out of the box improvement in uploading document performance when using FPSP instead of FSSP. In addition, if a user performs navigation, uploads, and downloads in accordance with the 80%/5%/15% distribution (user) model, overall uploads and downloads take an estimated 21% longer with FPSP scanning than without any scanning (baseline). This number can be significantly reduced by:
