SharePoint 2007 Maximum Limitations

Hi All,

Following is a list of names and other parameters with the maximum allowable size on each.

Entity          Max Permissible Size
Site Name           128 characters
Site URL            255 characters
Display name           128 characters
Connection string           384 characters
Email address           128 characters
Version numbers           064 characters
Virtual Server Friendly Name           064 characters
SQL Database Name           123 characters
SQL Database Column           128 characters
SQL Database Table Name           128 characters
SQL Role Name           128 characters
Server Name           128 characters
Windows User Name           300 characters
Windows Password           300 characters
Dependencies per object           032 objects
Zone enumeration value            004 zones
Default SQL command timeout            300 seconds
Number of simultaneous          
workflows that can be run*           015

It looks like the 15 limit Harsh mentions might actually be the WorkflowEventDeliveryThrottle, which is 15 by default. This throttle can be modified (see below) - try setting it to a very low number, and you should see that workflow activation slows dramatically.

SPWebService spWebService = SPFarm.Local.Services.GetValue<SPWebService>();
spWebService.WorkflowEventDeliveryThrottle = 20; // default is 15
