IIS and poor performance

[meo]

I write some code as following:

#1. myAppServer --tcp--> IIS ----> Web Application

#2. myAppServer --tcp--> Windows Application

The result is #1 is too slow when compared to #2 (around 3-4 times)

Actually I found the problem is in IIS 5.0/6.0 because of I am using the
same library (.dll) to connect to Application Server with TCP connection.

It is fast if I integrated dll to Windows Application but if I integrate to
Web Application, it is slow.

The performance is different around 4 times.

How can I do?

I suppose that IIS has some process to thinking and it cannot return the
message instantly.

meo,
without having the abiity to look at your code and what it does, I doubt
anybody here could provide mich help. Can you post a "Short but complete"
code sample?
