I just heard one of the clients having really bad performance on IE6 despite modern hardware and decent network connection. So we are suspecting either one or both to be the reason for the bad performance. Unfortunately no exact details of firewalls or such known at the moment... What kind of issues you have had with web applications us...
Hi! I'm writing some python and are stuck at the moment. I think this "Nagle algoritm" is the problem since my packages are delayed some time for some reason to the client. I've tried this on both client and server but it doesn't seems to work (or there's another problem causing it): socketobj.setsockopt(socket.IPPROTO_TCP, socket.TCP_...
I am about build a server on linux (I get to pick programming language) that accepts many TCP/IP socket persistent connections from a desktop software. How can this be done cheaply and efficiently? A machine cannot have more than 60000 ports, so if I have to support 600k connections then I will need 10 linux boxes? Since the computatio...
Possible Duplicates: Speed up File.Exists for non existing network shares Faster DirectoryExists function? We need to write text to a file on our network, but there may be a situation where that location does not exist and we need to write to another location instead. How do you check quickly that a network location exists? At...
Hi, How do I go about executing a fuzzing strategy to stress a network stack, specifically at the third and fourth layers (network and transport)? I've looked at frameworks to generate fuzzers, like SPIKE, but it seems to me that they are mostly focused on the application layer and above? Is there any well known techniques out there to ...

Is there a way to figure out the current data network available on iPhone? Whether it is EDGE or 3G? It works for me even if its doable using core telephony private framework. I am not bothered about app store submission. I know its very simple to identify whether the user is on Wifi or CellData network. But not able to find a way to i...
I wrote a .Net application that has nothing to do with network communication. There is not a single line of code in the whole application that uses the NIC, but my firewall has caught it trying to contact Verisign for some reason when the app starts. This does not happen regularly; as a matter of fact, it has only happened twice. The la...

We are running into some odd issues with streaming certain files in our app. After lots and lots of testing we've narrowed it down to what seems like some sort of issue between lighttpd and Droid, and it's not just our app but the built in player as well.
