Internet performance slowdown after installing IWSVA

When sized appropriately, and with recommended system requirements, IWSVA scanning, URL filtering, and other policy operations will not typically introduce a user- noticeable delay on Internet transactions.

For each instance of IWSVA installed on the network, you can expect it to comfortably handle 1000 concurrent connections (for a single CPU machine) with a less than two second performance impact.

Solutions

• Install IWSVA on a dual or quad CPU server—dual CPU supports 4000 concurrent users, while a quad can support 9000+ concurrent users

• Add another instance of IWSVA to the network

• Increase server memory (especially if you are using URL filtering)

• Increase the number of IWSVA threads
