I am building a c# application that resolves lots of domains into ip addresses asynchronously, using many DNS servers.

i am currently running 1000 requests per second on one windows 7 PC, when i try to run 2000 requests, it takes 2 seconds.

but when i try to run this extra 1000 requests on another windows 7 PC on the same LAN, simultaneously with the other PC, they both take 1 second to finish!

what make me think there is some sort of limitation on the amount of simultaneous asynchronous requests that can be made on a single windows PC.

any one has any input on that matter? thanks in advance!

    You are correct. The OS, and often even your network router, will have limits on the number of concurrent network requests. – Servy May 09 '14 at 21:03

  • I have no idea what limit you might be exceeding because there is not enough information in the question about what you're doing. – usr May 09 '14 at 21:19
  • Yuval Itzchakov, This refers to HTTP requests, i am doing DNS requests, it will not help. – user3535426 May 09 '14 at 21:25
  • Servy - It is not the router because i did the 2 PCs check on the same LAN – user3535426 May 09 '14 at 21:29
  • usr - What more information can i supply you? – user3535426 May 09 '14 at 21:31
  • Show your source code and provide your DNS settings. – EricLaw May 09 '14 at 21:36
  • EricLaw - My source code is too large to paste here, but i said what is relevant to the situation, and as for the DNS settings, as i said it runs on many DNS servers, non of which is relevant to the issue. – user3535426 May 09 '14 at 21:40
