• Performance of String literals vs constants for Session[...] dictionary keys

  - by FreshCode

  Session[Constant] vs Session["String Literal"] Performance I'm retrieving user-specific data like ViewData["CartItems"] = Session["CartItems"]; with a string literal for keys on every request. Should I be using constants for this? If yes, how should I go about implementing frequently used string literals and will it significantly affect performance on a high-traffic site? Related question does not address ASP.NET MVC or Session.

• Any big difference between using contains or loop through a list?

  - by Nazgulled

  Hi, Performance wise, is there really a big difference between using: ArrayList.contains(o) vs foreach|iterator LinkedList.contains(o) vs foreach|iterator HashMap.(containsKey|containsValue) vs foreach|iterator TreeMap.(containsKey|containsValue) vs foreach|iterator Of course, for the foreach|iterator loops, I'll have to explicitly compare the methods and return true or false accordingly. The object I'm comparing is an object where equals() and hashcode() are both properly overridden.

• Any benefits of using Windows Communication Foundation/ Web Services vs. a simple .aspx page for s

  - by Clay Nichols

  I'm working on a VB6 app that will do some very simple communication with a web server (passing value and getting back an anwer. Low bandwith and infrequent use). Someone suggested using WCF or Web Services. I'm wondering what the advantages are vs. just posting to an ASPX page like: Myserver.com/Functions.ASP?FunctionName=GetValue?UserName=BubbGump and returning some simple, easy to parse text, like one value per line.

• Open source equivelants to VS / web reference proxy class autogen?

  - by seraphym

  As an ASP.NET developer, I'm used to working with how VS/C# transparently autogens proxy classes for web references (yes, I know, we're spoiled), but now that I'm creating documentation for more than one coding platform I'm trying to discover what the equivelant to that is in any other framework. So is there a similar way to work transparently with web reference proxy classes for say, RoR, PHP, and Python? And if there's nothing integrated, are there tools you recommend to autogen the proxy classes, or do you recommend to roll custom classes?

• Why should I use a thread vs using a process?

  - by danmine

  I'm a newbie at this so please forgive me for my ignorance. Separating different parts of a program into different processes seems (to me) to make a more elegant program then just threading everything. In what scenario would it make sense to make things run on a thread vs separating the program into different processes? When should I use a thread? Edit: Anything on how (or if) they act differently with single core and multi core would also be helpful.
