How many IIS users share an application pool?

In the management area -- virtual host product definition, you can set the number of users in a pool.

On one server, generally, the total number of pools should not exceed 20 in terms of performance,

Therefore, the pool becomes a valuable resource.

The smaller the number of users in a pool, the higher the stability and performance of the pool. Therefore, the number of users in the pool should be associated with the charges, that is, the higher the charges, the smaller the number of users in the pool.

Generally, 50 people share the VM products that charge 100 yuan. 5 people who charge 1000 yuan are shared.

For a Shared Server (the total number of websites is less than 30), you can set the number of users in the pool to 1. In this way, a website is a pool, the "recycle pool function" and "set FSO function" are automatically added to the host panel, which gives these users more powerful control capabilities.

For free VM users, the number of users can be set to 20000 (20 thousand). This ensures that all websites are in the same pool, greatly reducing the memory usage.

The general principle is that the more the pool, the more memory is used, but the more stable a single website is, the less the pool is, the less memory is used, but the stability of a single website is reduced.

If you already have hundreds of websites and want to adjust them again, you can use the following tools to re-allocate applications.ProgramPool.
