Being a user with Win2k and IIS 5.0, I am reaching a little into the dark
here, however, a question comes to mind.  Does the server have DNS caching
turned on?   In IIS 5.0 running the caching service stores the lookup and
eliminates the need to do a lookup on each query.  If the service is not
running, then each query adds the overhead of the lookup and the response
before getting to work.

But I could be totally off base here.

Subject: Application Execution Time issues on Remote Share


Greetings,

Having a rather bizarre problem I'm hoping someone can shed some light on.

We are noticing some strange behavior from Cold Fusion while attempting to
employ a remote "resource" server architecture.

Basically, the head end web servers (WF40P1 & WF40P2) run IIS 4.0 and CF
4.5.1 SP2 and no code locally.  The home directory for the site is mounted
from a standard Windows File Share on the Resource Server (WF40R1).  This is
where all Cold Fusion code resides.

The site functions normally, but what we noticed at first was incredibly
slow application execution time compared to our stand alone servers.  We
predicted a small possibly degradation, but not 10 times slower.

After further review, and with full debugging on, we have seen the
following:

Application executes normally with all code local (Approx. 400ms)
When accessing the remote code base from the Resource server using the UNC,
we get up to 10 times slower execution time.
If we force IIS to map the Virtual directory to a statically mapped network
drive, we return to normal execution times.

So, in summary:
Local Code:  normal
Remote Code via UNC Share: Very Slow
Remote Code via Mapped Network Drive: Normal

I was hoping someone may have some insight on why this is occurring, and can
better explain what Cold Fusion is doing behind the scenes.  My initial
thoughts were that CF attempts to authenticate against the NT domain for
each resource (page) it is trying to access, or it is repeatedly doing a
name lookup of the resource server for each page it is retrieving.

Thank You,
-JD
