There is no single answer to this question, as it depends entirely on the network
bandwidth and IWSVA server hardware.
The goal, of course, is to install IWSVA on a server or servers with enough memory
and CPU power so that processing time can keep up with the flow of network traffic.
Properly sized to the environment, you can in general expect little or no delay from
Web filtering, blocking, and bandwidth management. For scanning, expect little or
no noticeable delay when downloading small files from the Web.
Larger files, and files with multiple layers of compression will take longer to process.
If the impact from IWSVA filtering, scanning, etc. is deemed to great, you can moderate
the load by adding additional instances of IWSVA to the network, optimize the HTTP
and/or FTP scan settings, and/or increase the memory and CPU available to IWSVA.
