I have a "High CPU usage" problem! Help me please!
-
Hi everyone. I have a coded a Proxy Server like code that works really fine for me! But there is an stupid problem! When I begin surfing the internet through my program (using the proxy setting in firefox) at the beginning, the CPU usage is normal with some times raising up to 2 and then back to 0 again, but as soon as I open 2 or 3 pages in firefox, specially the page with flv videos, the CPU usage raises up to 99 percent! Here is my TCP process code:
private void ClientConnectionHandler(object client) { TcpClient tcpClient = null; NetworkStream networkStream = null; TcpClient remoteTcpClient = null; NetworkStream remoteNetworkStream = null; try { tcpClient = (TcpClient)client; const int bufferSize = 1024; byte[] buffer = new byte[bufferSize]; tcpClient.ReceiveBufferSize = bufferSize; tcpClient.SendBufferSize = bufferSize; networkStream = tcpClient.GetStream(); int bytesRead = networkStream.Read(buffer, 0, bufferSize); string request = Encoding.ASCII.GetString(buffer, 0, bytesRead); string host = ""; string[] headers = request.Split(new string[] { "\r\n" }, StringSplitOptions.None); foreach (string header in headers) { if (header.ToLower().Replace(" ", "").Contains("host:")) { host = header.Replace(" ", "").Split(':')[1]; } } IPAddress[] hostAddresses = Dns.GetHostAddresses(host); remoteTcpClient = new TcpClient { ReceiveBufferSize = bufferSize, SendBufferSize = bufferSize }; remoteTcpClient.Connect(hostAddresses[0].ToString(), 80); remoteNetworkStream = remoteTcpClient.GetStream(); remoteNetworkStream.Write(buffer, 0, bytesRead); bool eof = request.Contains("\r\n"); while (!eof) { bytesRead = networkStream.Read(buffer, 0, bufferSize); remoteNetworkStream.Write(buffer, 0, bytesRead); eof = Encoding.ASCII.GetString(buffer, 0, byte -
