IIS Web Garden advantages / disadvantages

Question

When do you need IIS Web Garden feature. What's pro's and con's?

Answer 1

If you have a multi-processor web-server (and most environments do have one) and performance is low and CPU utilization is low as well, you might want to consider a web garden. The basic idea is that instead of a single worker process for the IIS Service, a garden has one worker process per CPU, thereby boosting performance.

Here is how to configure the garden.

Answer 2

Complete answer from David Wang.
Pros:

• An interim solution for faulty applications.

Cons:

• Worse overall performance.
• Prevent the use of session state in the process. So in statefull application you have another performance penalty to serialize the state to an external store.
