There are a number of commercial offerings that I've come across but nothing open-source.
I realise that you could do something simiilar with JUnit / JMeter but I'm looking for something a bit more specific.
What about clif
http://clif.ow2.org/
or jmeter
http://jmeter.apache.org/
I think there are others, but these two spring to mind.
You might want to have a look at Apache Jakarta Cactus
Jmeter + server logging + your brain.
Load testing is a very complex activity. You'll need to be able to simulate many contexts (e.g., IP, port) and divide the load generators on many machines. While doing that you'll need to monitor the server (Application under test).
As of today, there are several very good commercial tools that needs certain level of expertise to work with.
I don't think there is any serious open source load testing tool.

I'm gonna start developing a single page web application using Microsoft stack. In some critical parts of the project I have to provide real time data.
I can use Signalr or Web Sockets for these kind of tasks. Can you do a comparison of them in terms of usability, performance or learning curves of these technologies. And I'm glad to know if you have another option to suggest.
Thanks in advance,
I think you should go with signalR. It is part of .net framework, it also supports web sockets and if any client doesnt support web sockets it will fallback to long-polling, forever frames any other technology available.

I've never done networking stuff before so I am kind of confused. Suppose for example, I have a simple pong game setup. If I wanted to make that multiplayer in a sense that two people with different phone can play against each other, then ignoring the code to set that up what else do I need. So I need a dedicated server that handles the communication between the multiple users correct? Can I somehow make my mac into a server that handles that communication? What are my other options? Are there free servers that I can use which I can utilize into my game. I just need to put the pieces together because although I have decent knowledge about the whole project in pieces, I am not sure how to combine everything and put everything together. Can someone clear the uncertainty for me? Thanks.
For these cases I use Nodejs, Socket.IO and Expressjs, but usually free hosts do not have these software installed. But you can test locally from your Mac and your internal network.
Review post similars to:
Multiplayer HTML5, Node.js, Socket.IO
node.js and socket.io
Regards.

I am a student and I'm currently doing senior project. I'm required to work on the application control or application platform to let a group of programmer work together on a server with the security. I would like to know how a group of programmer work together on a server and how to work using visual studio 2010 on a server.
Thanks
First of all you have to use a version control system for your code such as SVN, which is one of the most popular.
There are also some other popular systems like GIT. You should try them both and see what fit your needs.
You'll probably want to create user accounts for each programmer on the server and allow them ssh access. Look into git for project version control.
i recommed your download here !

What are the features of R based Web Consoles? What are their advantages and disadvantages?
That's easy:
Rweb is pretty old, and a basic webinterface. The R FAQ lists more such webapps in its Section 4 on R and Web interfaces.
Webapps such as Rweb are for external third-parties, and mostly involve pre-canned code.
RStudio is new (and especially if running in web-mode on a server) a phenomenal new-school 'application as a webservice'. If running that way, or as a local app, it provides an IDE for R. That is different from a webapp.
IDEs such as Rstudio are for developers writing code. Theses IDEs are not facing unknown anonymous users.

I need a book to recommend strategies for load-testing an ASP.NET application with SQL Server backend.
Some info that may be useful:
how to write a load test plan
what perfmon counters to use and
typical threshold values
finding bottlenecks
various load testing tools
I can recommend two books published in 2010:
".NET Performance Testing and Optimization - The Complete Guide, by Paul Glavich, Chris Farrell".
"ASP.NET SITE PERFORMANCE SECRETS" by Matt Perdeck
The first book is pretty complete source for performance testing. It reflects all 4 topics listed in the question. The second book is written more from performance optimization standpoint, but also discusses in-depth bottlenecks, perfmon counters and load testing tools. It is also a free pdf eBook.
Microsoft has a Patterns & Practice book called "Performance Testing Guidance for Web Applications"
I haven't read it, but I've skimmed through it, and it looks like something that you or others would find beneficial. Plus, it's free.
