Dynamic site activation
When you are hosting a lot of web sites (100s) in IIS version 6/7/7.5, you may have experienced some noticable time when loading the IIS configuration file. When WAS runs it will load the configuration for all web sites hosted on the server. In IIS 8.5 a new more optimized process has been implemented to improve the performance of this activity. Note: There were also many improvements in this area found in IIS 8.0.
