I have folders around 3000 in my shared document library & it seems very slow when we use via webservice…

how can we tune up this folders in sharepoint to be fast response.

performance is needed right now!

i had created webservice to get site defention which retrives all folders & path enumerating.

>>Being new to SP, I noticed that when I use foreach to enumerate over the Items in a List, that I get huge memory bloat that does not release.

If you use the SPList.Items collection it will theoretically cache ALL the items in the list in memory (SPList objects). In lists with thousands of items this is not optimal, and in large lists it could lead to memory clutter. Much better is to use Views and Queries to return only the required items. I think you can divide the query into batches by setting the SPQuery.ListItemCollectionPosition and SPQuery.RowLimit properties. Basically it all boild down to using the Items collection as little as possible. us ItemCount to get the number of items.

>>is it possible to add a property to a list folder?

Each SPFolder object in a custom list has a corresponding Item object accessible through SPFolder.Item or SPList.GetItemByUniqueId(SPFolder.Item). You can get the folder’s properties using this SPListItem object just as you would with any other list item.

I believe you can. You just need to create a new content type based on the folder content type, and add the columns that you require to the folder.

Keith, is it possible to add a property to a list folder? I’m asking this because I need to show the items and folders of a Sharepoint list in an application outside Sharepoint. They have to be shown in a specific order, something like this:

Item #1
Folder #1
Subitem #1
Subitem #2
Subitem #3
Item #2
Item #3
Folder #2
Subitem #1
Subitem #2
Item #4
Item #5

So I thought of solving this by using a property (or something of the sort) in the folder, just like a column in the list item, to store the display sequence number.

How can I do that?

Keith, thanks for the quick reply. I will take a look at the article, but I am already properly disposing of my Web and Site references.
Is there a way we can take this conversation “off-line” so as to not clutter up your blog?

Not sure the direct calls your making during the enumeration, but if you are accessing the lists ParentWeb, it will instantiate a new SPWeb instance that you should call dispose on.
