Hi,
We have developed a server program using TCP/IP Communication to communicate with another client program. After running for some days we find the TCP/IP connection from the server program is getting slower ie, the messages are not send quickly to the client.

What i mean to say is since the tcp/ip send() function in the server program is in the blocked mode, we suspect the reason for the slowness in sending the message to the client program could be because of the TCP buffer (in the server)getting full and the clients failure to pull the messages from the buffer in time.All these has being coded in a posix thread. Once the buffer is full, the send() function is blocked until the client pulls some messages from the buffer, the send() doesn't return.

We have been perplexed by this problem for quite a long time. we intially though it could be the network problem..but the network is 100Mbs..

The hardware used is sun solaris machine..

I will be very grateful if some one can advice us in finding a solution for this problem.
