Hello Igor,
>> obtain an error 10035 from time to time during a communication. In witch event do you have this error ? It should normally never occur because it it handled by TWSocket. >> meaning the communication is slow... about 1000 byte per a second A PII-300 machine can easely saturation a 10 mbps network with TWSocket, So if you dont get this performance something else is wrong. How do you do your test ? If you dont get higher than 1000 bytes / second then eather your server or your client is doing 100% CPU on his machine. Whitch one ? Because that's the one to investigate. --- Rgds, Wilfried http://www.mestdagh.biz Hello Wilfried, I do know my machine (server) is below 6 per cent using CPU running this task only. I will check the client machine on Monday. The client asks for data sending 24 byte long record. The error gets mostly when I obtain three or more asking in one frame. The producer of the client application told me every asking wait for an answer before to send another. He uses more threads I guess. Never the less I am curious only because as Francois noticed, there isn't any problem with a communication. When I didn't write a procedure for OnError, I could have slept better :-) Regards Igor -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
