TCP/IP Connection getting slower...
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.
What i mean to say is since the send() function in the server program (it is in the blocked mode)is blocked, 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 is being coded in a posix thread.
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.
