With a Weird Issue Started last week SharePoint 3 Slow Upload from Browser.

Now when you use the Upload from the website GUI it is fine
From the "Server Browser" it is fine.
But the User's PCs it is slow

So I uninstalled Trend Micro on the PCs
Still Slow,

I Ran IE without Plug-Ins still Slow
I even tweaked the Data packets for IE

And it still is slow..
Takes about 1.3min to load a 5MB file to SharePoint from the Browser on a
PC.
Most of the time it says Calculating..... and Sits...

An Ideas?
Thanks
Russ

Hey Russel,

A few things to try

- Are the slow updates happening on all client PCs or only on some? What
about computers that are not part of the domain?

- Are all files taking long time to upload or only specific types (.docx,
.pdf)?

- Are the problematic PCs running the same version of IE? Is it the latest
one (IE6 had a default registry setting that would cause slow uploads) ? Is
the server running the same version?

- Are uploads from other browsers fine (Chrome, firefox)?

- Have you tried disabling the AV on the server temporarily?

- Have you tried uninstalling any updates applied in the last 2 weeks?

- Are you uploading to an HTTP or HTTPS site?

- Is anything unusual happening to the server CPU load, memory usage or HDD
activity when files are being uploaded. How about the client PC?

- Try uploading the file using the "Upload multiple documents" feature - is
the performance as bad as using the single file upload?

- Try uploading the file using the explorer view (WebDav) - any difference
in speed?

- Have there been any changes made to the server in the last 2 weeks - any
changes to networking settings (e.g. NIC Duplexing)?

- Is the server updated with all latest updates?

- Check your content databases - it might have reached the max space and is
being expanded dynamically as the file is uploading. If the auto-growth
setting is set to 1Mb sharepoint can grind to a halt (although you mentioned
uploading files from the server itself seems to be fine so this is probably
not the cause)

- Try sharing a folder on the Sharepoint server and try uploading files to
the folder from the client PCs - if the performance is slow as well this may
indicate some networking issues (routing, duplex settings etc.)

Hope this helps,
Greg Osimowicz

OK thanks that is a lot
All PCs Win7 64bit 8GB Ram
Joined Domain
All using IE (version with win7)
from the server IE it copies fine.

All is http (no https)
File not specific

I didn't disable the server AV
because from the Server it copies fine.

So it seems to be a PC related
No updates on the server when it started.

PC's unknown. (I couldn't' see anything like a av added or anything)

From the webdav Upload GUI sharepoint the file copy is quick

When you upload from the browser
it shows a 1/4bar and says calculating
and then takes for ever before it copies

I've turned off sleep in IIS for Sharepoint (Thinking that was it.)

Restoring a PC to a previous point before this
Is a good idea.. BTW thanks...

I've checked so many things I can't remember if the shared folder does it?
But wouldn't that be the same as opening in IE?
???

Thanks
Russ

So are you saying uploads via the Explorer view work fine? Strange - usually
it's the other way around :)

I would do 3 things to further narrow down the problem:

1. Check uploads from a PC that's not part of the domain - this is to make
sure that the issue is not related to any settings pushed to client PCs via
group policies.

2) Check uploads from other browsers
- You'll know if the issue is specific to IE or not. If it you know you need
to focus your troubleshooting on IE, if the issue applies to all browsers
than it's most likely there is something affecting the HTTP traffic between
the server and the client - see the point below.

3) Check if you have ISA or any other firewall sitting between the server
and the client PCs. Is there any other publishing mechanism in place (e.g.
ISA or some proxy that would involve HTTP re-writing)? If there are, can you
connect a laptop to the same switch that the server uses and configure
routing on the laptop for traffic to go directly to the server. Also, are the
clients and the server connecting using the same URL? Try connecting via IP
address and see what happens.

Cheers,

A client from New Jersey Contacted me today

So I uninstalled Trend Micro on the PCs

And it still is slow..
Takes about 1.3min to load a 5MB file to SharePoint from the Browser on a

Most of the time it says Calculating..... and Sits...
An Ideas?

Well now it's on hold because he says his PC is the only issue?
And he's out of the office for the rest of the week..

SO I'm on hold, Thanks
