Okay. Thanks for taking the trouble to tell us. I am not sure exactly what the 
problem is: Freenet runs at BELOW_NORMAL priority, so even if it does use the 
CPU heavily (and it shouldn't, most of the time), other applications should get 
to run first.

Generally the causes of heavy CPU usage in Freenet are:
- Running out of memory. The settings in wrapper.conf determine how much memory 
Freenet can use, and if it is approaching the limit it can end up using a lot 
of CPU to try to scavenge the last few bytes. The solution is to increase the 
limit. We have some code for auto-detection but it's not deployed yet, sorry.
- Filesharing. Decoding and encoding splitfiles, compressing and decompressing, 
if you queue downloads or especially uploads you can expect periods of very 
high CPU usage.
