Boost asio::async_write sending thousands of small packets

Question

In my application I have to send about 10 kb/s per connection. All packets are put in a std::deque. One thread iterates over the deque and sends packet data via asio::async_write.

My question is how much connections can I handle simultaneously in one thread? Can I send say 20 Mbytes/s?

Answers on this question dont say can i send megabytes of small data chunks per second. — Denis Ermolin, Apr 24 '12 at 07:22
depending on the packet size, 20MB/sec/thread can be possible. you can always use a few threads and not one and make use of more than one core. — Not_a_Golfer, Apr 24 '12 at 07:33

The Boost.Asio author Kohlhoff's website has a performance page. Looking at the graph of Linux-perf-11, he gets a throughput of ~300 Mb/sec with 1000 connections on a single CPU, which is way above your target of 10kb/sec per connection.
