Re: Communication speed between blocking call and non blocking cal

Do you mean you increased TcpWindowSize ?
TIA

Hi
Thanks for reply.
Ultimately I have got good speed with non blocking socket. speed is around
97Mbps.
Problem was I did not set winsock kernel buffer. Now I set buffer size
5MB.

Can't imagine a reason not to. I have no problem with non-blocking
socket and regular select for sure. Make sure you are not starving
the socket - e.g. you always fill its send buffer. Or if it's a receive
socket - make sure you drain it completely before waiting for
another event. You may get notified with no data in the socket
this way - simply ignore such cases.

Hi
Thanks for reply.
It is TCP socket.
Code is big because it includes business logic also. So i could not
post
in
newsgroup.
Are we sure nonblockin socket gives high speed with WSAEventSelect???

Can you post your code for review? May be a programming
error on your part...

Also, are you talking about sending or receiving data? TCP or
UDP?

Hi

As we know there are two main methods for socket communication
1. winsock blocking calls
2. winsock nonblocking calls

I would like to know that which method is faster.
As I tested blocking call is much faster than nonblocking call
(WSAEnumNetworkEvents).

Blocking call gives me speed around 80Mbps whereas nonblocking
call(WSAEnumNetworkEvents) gives me around 10Mbps.
Please suggest me that How to increase speed for nonblocking
call(WSAEnumNetworkEvents).
I tested under windows 2000 Server.
