Performance problems IIS 6.0 running in IIS 5 (Isolation Mode) vs.Worker Process Isolation Mode

Hi,

I have setup a IIS 6 server and I'm in the process of moving some ASP
applications that were hosted on a server running IIS 5. The ASP
applications are requesting data from an Oracle database hosted on a
separate machine.

When the IIS 6 server is setup to run in IIS 5 Isolation Mode the
performance of the ASP application is very fast versus running the same
application on the same IIS 6 server running in Worker Process Isolation
Mode.

In IIS 5 isolation mode the page is returned in 5 seconds, in Worker Process
isolation mode the same page is returned to the client in 1 minute.

Any ideas of why IIS 5 isolation mode is so much faster? Any help will be
appreciated.

Thanks.

Seems like something specific to your application. Perhaps your application
has has issues not running inside of a process named inetinfo.exe (i.e.
code that looks like "if not in inetinfo.exe, then sleep for 60 seconds" )
or cannot run multi-instance (worker process isolation mode allows this).
The same core web server DLLs are executing your web pages...

You can use IIS State during that "minute" of execution under Worker Process
Isolation Mode to see what is taking so long and troubleshoot from there.

Lorenzo,

Try this suggestion. It is works fine for similar issue.

A new registery key needs to be created in the Window 2003 Server:

HKLM\SYSTEM\CurrentControlSet\Services\HTTP\Parameters\EnableCopySend of
type of DWORD, value set to "1"

After rebooting server computer check performance again.

Let me know, please, if its suggestion works for you also.

Nikolay,

The Registry key entry did not work, still slow.

David,

I tried using IIS State but I am not sure how to read it. Following are the
results. Any help will be appreciated.

Opened log file 'C:\iisstate\output\IISState-3556.log'

Lorenzo,

What data amount are you transmit from server to client? Is problem persist,
if you eliminate network time costs (for example, using client application
on server box)?
Did you try to monitor network traffic (for example, via Netwowk monitor
from MS) between client and server? If yes, can you see strange 200 msec
holes (delays) on it?

Nikolay,

The problem persists if I run the application on the server.

I looked at network traffic but could not see the 200msec delays.

Nikolay,

I just tested the slow page from the IIS server and it comes back fast.
From a users PC it is very slow.

Lorenzo,

A few weeks ago we worked at the same migration issue from IIS5 on Win2000
platform to II6 on 2003 box. We discovered the same performance issue as you
described earlier. After some work with MS support we got suggestion that I
wrote in previous post. It works fine for us. Today I discovered official
bug description about this issue at
http://support.microsoft.com/default.aspx?scid=kb;en-us;840875

So, I think it should work. First of all, double check your additional
parameter (this MUST be DWORD type) in Win2003 server registry.

Secondary, try another registry setting on CLIENT machine. In TCP settings
need to add next DWORD value TcpDelAckTicks and set it to 0.

Value location is Tcpip\Parameters\Interfaces\interfaceGUID.

This is workaround only because should be implemented on ALL clients, but
if it works it shows that the root of problem is the same.



Good luck,

Nick

Nikolay,

I just tested the slow page from the IIS server and it comes back fast.
From a users PC it is very slow.

Nikolay,

Strange thing, looks like my pages are being served to the client very fast
now. The thing is I did not do anything. In order to troubleshoot I had
setup 2 web servers both running W2K3 with IIS 6 in worker Isolation Mode,
each on a different network segments, each communicating to the database
server via different routes. On both web servers I could duplicate the
problem consistently from my client and I also tested it from other clients,
same results. One of the web servers has the new registry entry the other
does not.

Now, without doing anything my pages are served very quickly. I don't
understand it, am I having network problems? I don't think I am since I was
able to get the pages served to the client fast if I switched both web
servers to IIS 5 Isolation Mode.

Any clues or ideas as to what is happening?

Thanks.

Lorenzo,

Very strange... Looks like miracle. May be server rebooting or client page
caching?
Try to reboot servers again and check reg settings thoroughly on clients and
server boxes.
