Difference between IIS 5.0 and IIS 6.0 architecture
-
Hello People, I have been trying to understand the difference between IIS 5.0 and IIS 6.0 It states that there is a kernel level process called as Http.sys which will route the message to the appropriate application pool which is not the case with IIS 5.0. Wat Iam not able to understand is how this will give significant performance improvement? Becos in IIS 5.0 the request message is sent from inetinfo.exe to aspnet_worker process which involves interprocess communication. Similarly in IIS 6.0 the request message is being sent from Http.Sys to w3wp.exe wherin there is inter process communoication. So the question as how the performance is improved by having Http.Sys remains unanswered.... COuld any one throw more light and give a very clear picture stating as how the performance is increased in IIS 6.0? Thanks in Advance!!!!!!!!! Vivek

Could be that performace is not improved by having Http.Sys, but rather by how Http.Sys is implemented. Perhaps its better written?

Mite be!!!!!!!!but Wat microsoft is instisting is that the http.sys runs in kernle mode which is why it is improves the performance....If some one can throw light on how a soft ware running on kernel mode can improve the performance
