Hi I have a document list (MOSS 2007) with 600 items that is rendered very slowly when accessed via Site Manager, each time. Custom webpart is also slow when accessing this list, but the list is fast when accessed directly with MOSS standard view. Does anyone know why this is happening? Thanks

Hi Aerotodorr, Thank you for your question. I am trying to involve someone familiar with this topic to further look at this issue. Thanks, Lhan Han

if you wrote the custom web part or have access to the code, you can add the SPMonitoredScope to the web part code and use the dashboard designer to track where the slow execution of the part is occurring.

Hi, Turn on verbose mode of logging nad carry out your activities and capture the issue details in ULS logs.Thanks, Rahul Rashu

Hi, When you are looking at items in Site Manager it pushes all of the items into an array before you see it rendered on the screen. You can see this happening if you watch the ULS logs in verbose mode. See how long it takes to build the array based off that. It will be a little slower since it has to do this when compared to other methods. Also please let us know your definition of slow and fast. The server that you are testing on, does it meet the minimum hardware requirement specs? http://technet.microsoft.com/en-us/library/cc262485(v=office.12).aspx The slowness in the custom can be caused on how you are retrieving the data. Please ensure that best practices are followed for retrieving data. http://msdn.microsoft.com/en-us/library/bb687949(v=office.12).aspx Are you seeing any abnormal CPU usage on the SharePoint server or the SQL server when you are using site manager or the custom webpart? Is the SharePoint server x86 or x64? If it is x86 check to see if the memory usage pattern is reaching the automatic recycle threshold set in IIS. Make sure you keep eye on the ULS log to see if there are any errors being thrown during processing of this request. This should help you clue into what is causing it.Regards, Savoeurn Va Microsoft Online Community Support
