For some particularly busy websites, IIS log files can be very large. I used to have a client with 2 grams per log file. Such a large file is very slow to analyze with logparser, and it is easy to make an error. The solution is to split the log file into a number of small files for analysis separately. The

Strong ref (strong quote): Usually we write code that is strong Ref, which corresponds to strong accessibility, and the object is recycled only if you remove the strong. Soft Ref (Soft Reference): corresponds to soft accessibility, so long as there is enough memory, the object is persisted until the memory is found to be tight and no strong Ref is collected.

Dimension cache in Analysis Service 2005 SQL Server 2000 and SQL Server 2005 separate profiling services vary greatly when working with dimension members. In SQL Server 2000, all dimension members in all databases need to be loaded into the server's address space at startup. In this case, memory cannot provide a good service for other programs, and the data cache will exceed the dimension's memory. That's a big limitation. This means that on a 32-bit
