Sharepoint Server 2010 is slow.. especially when uploading large files/creating new sites

Hi
I'm setting up a Sharepoint 2010 site (I'm grateful for everyone's advice from this site!) but it seems very slow whenever I create a new site, or upload large file.

For example, I upload a 50mb file... it's very quick. I upload a 500mb file, and that's quick until it gets to "processing..." - "please wait while your changes are processed".

The site is for a media company, and we need to upload large files. The server has memory left, and the CPU usage is quite low.

The Sharepoint setup is on the same server as the SQL 2008 standard database.

Please help!!!

Hi,
it is a known problem. First, read this article and update settings to support large files upload:
http://blog.gavin-adams.com/2007/06/28/configuring-large-file-support/

Pay attention to this solution, seems it solves problem:
http://support.microsoft.com/kb/944981

Then pay attention for IIS Add-ons, like URLscan, which can cause delays scannig files.

Also Antivirus can take quite some time to scan a file.

Nvertheless, if you have fast NIC adapters, observer uploading graph with large files. Faster NIC's use system memory for buffering, and when buffer is full, upload almost drops to 1% of maximum, and 5-30 seconds delay occures until buffer flushes. I don't know how to solve this, except of using as dumb NIC driver as possible (Intel E1000, for example).

Maybe you can try NIC teaming on your server?

Hi - files are actually slow to upload from the server itself... so I don't think it's a NIC issue.

Thanks

In my previous answer you may see, there are IIS timeout problems when loading large files. I'd follow the suggested article and report back with results.

Hi
Thanks Labsy, but I've gone through all those links you gave me and none of them have improved the problem. I'm not sure it's a file size issue.

When I simply try to create a new site, it takes three minutes of the screen "processing.. please wait while your changes are being processed"

-that makes me think something else is going on for it to be happening to uploading files (some less than 30MB) and when creating new applications/sites.

New ideas?

Hi
Small files go so fast, the speed seems directly proportional to the size of the file.... I wondered if it's the time it takes to actually insert the file in to the SQL Standard 2008 DB?
