• Using Predicate of a class to Search Generic list - Faster than looping?

  - by Srikanth

  Lets say we have a generic list of Class1, typically having ~100 objects for a given session. I would like to see if the list has a particular object. ASP.NET 2.0 allows me to do this: Dim objResult as Class1 = objList.Find(objSearch) How does this approach rate when compared to a traditional For loop, looking at a performance perspective? How would this vary with increase or decrease in length of the list?

• TSql Lookup function

  - by OldMan

  I have a bunch of dimension tables that have unique ID and Name fields. I need a T-SQL function that returns an ID when passed a table name and a value for the name field. I'm guessing the query would build a little query then execute it? Performance isn't an issue since this is a one time ETL thing.

• Is it possible to unpage all memory in Windows?

  - by Hack59

  I have plenty of RAM, however, after starting and finishing a large number of processes, it seems that most of the applications' virtual memory has been paged to disk, and switching to any of the older processes requires a very long time to load the memory back into RAM. Is there a way, either via Windows API or via kernel call, to get Windows to unpage all (or as much as possible) memory? Maybe by stepping through the list of running processes and get the memory manager to unpage each process's memory?
