I am having trouble with our custom web application. We
just upgraded to window 2003 and have seen a decrease in
performance running the web off of this server. It is
not consistent though, because XP users and some W2K
users have not seen a decrease in performance. All W2K
users are running SP3 and have the latest version of IE.
I have seen in some instances where adding the Qos Packet
Scheduler service to the local area connection did bring
the slow clients up to speed, but for others it did
nothing. I also looked into the buffering issue, and
when buffering was turned on it did help, but due to our
code this is not an option. I would really like to know
what the real issue is here, because if it is buffering,
why are there still mixed OS clients still running the
App at normal speed. I would appreciate any info or
tips....thanks

Your issue does not sound like the buffering issue since that will happen
uniformly for all clients.

You want to look in %SYSTEMROOT%\System32\LogFiles\HTTPERR\*.log to see if
there is anything unusual in there.

As for the "real issue" in your case, we'll just have to try to
systematically troubleshoot and figure it out -- that's what a
server/webmaster is responsible for.

David,

We have an ASP app that runs perfectly accross all
clients when hosted under IIS 5. We moved the same code
to IIS 6 and *some* windows 2000 clients are loading
pages painfully slow. The pages are not exceptionally
large...only 80-100k. All code has Response.Buffer =
false. However, when we enable buffering, all clients
perform the same. Why would it be slow on a per client
basis when switching hosting from IIS 5 to IIS 6 and only
on some W2K clients but not on any XP clients?

btw...we looked at the log file and there are no errors.

So, you are saying that for the EXACT SAME PAGE and result-set, SOME W2K
clients would access it very slowly but not other W2K clients, and XP
clients do not have a problem?

If that is the case, the Response.Flush() issue that you've been reading
about isn't the cause -- that issue would affect all clients that encounter
the same code sequence.

Are you also saying that when you enable Buffering that all clients perform
well or not well? What code sequence is requiring you to have Buffering =
false?

Without more investigation and info on the characteristics of your pages
(such as what it's doing), I wouldn't know what's going on in your
situation, much less why.

BTW, 80K page is HUGE. Dialup users wait >15 seconds just for the page
itself.

When buffering is enabled ALL clients perform well. When
it is disabled, we see the inconsistent results on W2K
clients.

This is an intranet web application, so page size is not
really an issue. All of the clients are running at
10/100. In addition, all clients use IE only. Network
is not the issue.

Regardless of what the page is doing, the bottleneck is
occurring when it is downloading the page results to the
client, not processing the page. We have an include file
in the page that has javascript code. This is a very
large include file and the majority of the time is taken
while downloading this portion of the page.

I really can't think of anything else other than to get a NetMon capture of
one of the unfortunately clients accessing a page slowly.

You're saying that there's no errors in HTTPERR log files during all this,
so data is being sent, connections are not being dropped... but causing
clients to be slow... so I can only think of using a network trace to
capture one of those sequences and see what's going on.
