Hrmm... false alarm. I believe there was something wrong with my kernel (specifically with my cpufreq -- my max cpufreq didn't seem right, and, actually, most of my programs seemed sluggish, although freenet especially so. Adding the userspace governor fixed things.)

[freenet-support] Something is wrong with my java.net code?
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.
