In perfmon I can not see any aspnet_wp instance under any objects, instead I see many other instance and w3wp instance.

What is difference between these two ?
Is that w3wp is the aspnet_wp equivalent in IIs 7.5 ?

I found that aspnet_wp.exe is no longer used in IIS 6.0.

I use II 7.5,so can I use w3wp instance counter instead of aspnet_wp ? Gives me the same result ?
