I switched my hardware recently, and now Freenet (or something) is having trouble running. It consumes about 100% CPU, and very little data goes manages to flow.
I ran an HPROF (cpu=samples,depth=30) on it, and here are the Top 10 culprits: CPU SAMPLES BEGIN (total = 479392) Tue Nov 2 20:31:28 2010 rank self accum count trace method 1 28.90% 28.90% 138567 300769 java.net.PlainSocketImpl.socketAccept 2 9.46% 38.36% 45351 304459 java.net.PlainDatagramSocketImpl.receive0 3 8.43% 46.79% 40398 300330 java.net.SocketInputStream.socketRead0 4 6.56% 53.35% 31429 305339 java.net.SocketInputStream.socketRead0 5 6.54% 59.89% 31355 305536 java.net.PlainSocketImpl.socketAccept 6 6.54% 66.43% 31341 305569 java.net.PlainSocketImpl.socketAccept 7 6.52% 72.95% 31273 305094 java.net.SocketInputStream.socketRead0 8 1.40% 74.34% 6689 309110 com.onionnetworks.fec.FECMath.addMul 9 0.83% 75.18% 3980 304968 net.i2p.util.NativeBigInteger.nativeModPow 10 0.82% 76.00% 3944 304998 net.i2p.util.NativeBigInteger.nativeModPow With the main one being: TRACE 300769: java.net.PlainSocketImpl.socketAccept(PlainSocketImpl.java:Unknown line) java.net.PlainSocketImpl.accept(PlainSocketImpl.java:390) java.net.ServerSocket.implAccept(ServerSocket.java:453) java.net.ServerSocket.accept(ServerSocket.java:421) freenet.io.NetworkInterface$Acceptor.run(NetworkInterface.java:325) freenet.support.PooledExecutor$MyThread.realRun(PooledExecutor.java:228) freenet.support.io.NativeThread.run(NativeThread.java:101) Followed by: TRACE 304459: java.net.PlainDatagramSocketImpl.receive0(PlainDatagramSocketImpl.java:Unknown line) java.net.PlainDatagramSocketImpl.receive(PlainDatagramSocketImpl.java:136) java.net.DatagramSocket.receive(DatagramSocket.java:725) freenet.io.comm.UdpSocketHandler.getPacket(UdpSocketHandler.java:193) freenet.io.comm.UdpSocketHandler.realRun(UdpSocketHandler.java:149) freenet.io.comm.UdpSocketHandler.runLoop(UdpSocketHandler.java:135) freenet.io.comm.UdpSocketHandler.run(UdpSocketHandler.java:92) freenet.support.PooledExecutor$MyThread.realRun(PooledExecutor.java:228) freenet.support.io.NativeThread.run(NativeThread.java:101) TRACE 300330: java.net.SocketInputStream.socketRead0(SocketInputStream.java:Unknown line) java.net.SocketInputStream.read(SocketInputStream.java:129) java.net.SocketInputStream.read(SocketInputStream.java:182) java.io.DataInputStream.readByte(DataInputStream.java:248) org.tanukisoftware.wrapper.WrapperManager.handleSocket(WrapperManager.java:4203) org.tanukisoftware.wrapper.WrapperManager.run(WrapperManager.java:4558) java.lang.Thread.run(Thread.java:662) TRACE 305339: java.net.SocketInputStream.socketRead0(SocketInputStream.java:Unknown line) java.net.SocketInputStream.read(SocketInputStream.java:129) java.net.SocketInputStream.read(SocketInputStream.java:182) java.io.FilterInputStream.read(FilterInputStream.java:66) freemail.support.io.LineReadingInputStream.readLine(LineReadingInputStream.java:32) freemail.fcp.FCPMessage.<init>(FCPMessage.java:62) freemail.fcp.FCPConnection.getMessage(FCPConnection.java:184) freemail.fcp.FCPConnection.run(FCPConnection.java:91) java.lang.Thread.run(Thread.java:662) TRACE 305536: java.net.PlainSocketImpl.socketAccept(PlainSocketImpl.java:Unknown line) java.net.PlainSocketImpl.accept(PlainSocketImpl.java:390) java.net.ServerSocket.implAccept(ServerSocket.java:453) java.net.ServerSocket.accept(ServerSocket.java:421) freemail.smtp.SMTPListener.realrun(SMTPListener.java:69) freemail.smtp.SMTPListener.run(SMTPListener.java:51) java.lang.Thread.run(Thread.java:662) TRACE 305569: java.net.PlainSocketImpl.socketAccept(PlainSocketImpl.java:Unknown line) java.net.PlainSocketImpl.accept(PlainSocketImpl.java:390) java.net.ServerSocket.implAccept(ServerSocket.java:453) java.net.ServerSocket.accept(ServerSocket.java:421) freemail.imap.IMAPListener.realrun(IMAPListener.java:68) freemail.imap.IMAPListener.run(IMAPListener.java:57) java.lang.Thread.run(Thread.java:662) The top 7 are all java.net related, and stand head and shoulder above what one should sanely expect to be the highest cpu consumers (FEC stuff).
