If you can bring yourself to punch that hole in your firewall, I consider pushing bits an Ubuntu or ISO of your choice around the globe to be a effective and humanitarian test case.

I believe that the problem lies in our NIO implementation. I don't know exactly what the problem is. It has been discussed a few times on some of our mailing lists (GNU Classpath, [EMAIL PROTECTED]).

If by precompiled classes you mean compiled to native code using GCJ, Debian doesn't have native binaries for Azureus, and it isn't set up to use the native binaries for SWT. I agree with you that I don't think that's the core issue though. Perhaps Azureus is using some unusual networking API that perhaps GIJ/classpath doesn't support. It's odd to me that it does run, and does download a few bytes, only excruciatingly slowly. Cheers, Shaun -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

Hello Andrew, I can confirm that the CPU usage is <5% and that the precompiled classes are being used. Lots of messages like [Loaded (pre-compiled) java.lang.ClassLoader from ] I do see messages like this: DEBUG::Wed Nov 21 11:05:54 GMT-07:00 2007::com.aelitis.azureus.core.networkmanager.impl.tcp.VirtualChannelSelectorImpl::select::586: VirtualChannelSelector: No progress for op 1: listener = class com.aelitis.azureus.core.clientmessageservice.impl.NonBlockingReadWriteService$2, count = 300, socket: open = true, connected = true VirtualChannelSelector::select::332,NonBlockingReadWriteService$1::runSupport::82,AEThread::run::69 Perhaps it's related.

If the CPU is pegged at 100%, I'd do some profiling. Also, starting with the vm option -verbose:class will tell you if, by some accident, you aren't using the precompiled classes.

Bug #449176: azureus: Downloads very slowly with GIJ
Running the bit torrent client Azureus, downloading progresses terribly slowly with the java-gcj-compat JVM and works fine with Sun's JVM. If anyone has any thoughts on why this might be the case, or has some time to investigate, I'd appreciate the help in solving this bug. http://bugs.debian.org/449176 Cheers, Shaun -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
