The data received is of no importance. I just measure the speed an how many concurrent downloads. I've implemented 2 different ways of scheduling 12 HTTP-requests. What I observe is that in both cases the 6th to 12th request get a TimeOut errorcode If 1 put the timeout-value to You can have maximum of 5 simultaneous connections to the same server.

It's an iOS fixed limit and it's probably because of some http protocol constraints. You can read a bit more info here. Just a bump to this in case anyone is still looking. Here were my test steps:. The results are like clockwork. The first responses 4 of them come back 12 seconds after the request presumably 2 seconds to turn the radio on or whatever , but then each subsequent block of 4 responses come 10 seconds after the prior block of 4.

All 4 at a time. This property determines the maximum number of simultaneous connections made to each host by tasks within sessions based on this configuration. This limit is per session, so if you use multiple sessions, your app as a whole may exceed this limit. Additionally, depending on your connection to the Internet, a session may use a lower limit than the one you specify. This is, by the way, a per server-based limit, not an iOS limit.

If you try doing this from different servers at the same time, you will see that you can exceed your current limit. Obviously you could do something with GCD, too, manually managing concurrent requests, but I think NSOperationQueue is an excellent solution and see no reason to look further than that.

I certainly don't see any advantages to using threads, either. You should benchmark the total elapsed time as the number of concurrent requests increases, but I'm sure you'll hit a point of diminishing returns. Just having more concurrent requests does not ensure better total performance. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams?
