IO completion port for Client

[keenlearner]

I am learning to build a web robot for my own interest, I saw lots of article building scalable server using completion port which can accept lots of clients efficiently. However, I am thinking of how can I use the features of IO completion method in building client application such as web robot to increase the efficiency of crawling. I want to make request to many servers at the same time, such as maybe I create lot of sockets to request web pages to many servers and then a few worker thread (thread pool) will process the IO completion request (server html response). Is it possible to do this ? Or what other things that I can benefits from using I/O completion for Client TCP ?Thank you

IOCPs give the same benefits to clients as to servers.

But you tend to use IOCP less often in clients, since the number of simultaneous connections is typically far fewer than in servers.

You need to evaluate for yourself whether the added programming complexity of IOCPs is worth the effort for your client.
