Java is highly multithreaded and often benefits from hyperthreading. But
yeah, if you're network-bound, won't matter.

Ah. That's not the source code. There's only one source code, but there's
different -devel packages, which contain headers prepared for the particular
built kernel.

Right, that is one of several problems with the Cisco binary client. I
highly encourage you to try vpnc instead -- it is included with Fedora (part
of Fedora Extras -- just 'yum install vpnc' and perhaps 'yum install
NetworkManager-vpnc'). You'll not need to compile anything, nor taint your
kernel, and it works very well.
