Do you receive data each time you call ReceiveStr ? If yes, then probably you have a fast network, and your application becomes CPU bound. btw: Since you don't use line mode, I strongly suggest you avoid ReceiveStr and instead use Receive with a fixed buffer. Calling ReceiveStr will force the runtime to create new string and copy data into it, and probably youthen copy data elsewhere for processing. All this is very CPU intensive. The best way to design a high performance application is to use a fixed buffer (which may be dynamically allocated but not each time you receive data). And use the buffer as close as possible of the processing each time you copy data, each time you consume CPU and memory for nothing. -- [EMAIL PROTECTED] The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
