I just want to spout off about my node's performance, or lack of it.  I'm running a permanent node on a server that has other things to do besides spend every cpu cycle on a java app.  Also, like alot of node operators, I don't use the machine directly, but instead access fproxy and fcp from another machine.  Sometimes it can take SEVERAL minutes just to call up the web interface!  Even when I do finally get through, alot of content is simply not found, no doubt due to overloaded permanent nodes.  Here are some suggestions for the developers:
 
Transient nodes should be your lowest priority right now.  Attention should be shifted to the permanent nodes because the health of the network depends on them.  That means that CPU utilization needs to be reduced drastically.  Performance for FCP and FProxy need to get the HIGHEST priority when the node is processing.  If that means that other transactions have to be put on hold in order to process a local request, then so be it.  Permanent node operators should not be penalized for serving the Freenet community. 
More should be done to encourage people to run permanent nodes.  Requests could be prioritized by each node according to the requesters responsiveness and availability to that node.  Of course some minimum level of resources need to be dedicated to slower nodes to prevent the network from fragmenting.  To help those who are firewalled or using NAT (who have trouble receiving inbound connections, but not establishing outbound connections), nodes with a permanent IP could also serve as helpers, by listening on behalf of a firewalled or NAT node.  This would only be required for establishing connections, NOT for acting as a proxy for the data.  Bandwidth requirements would be minor and would allow alot of people to become permanent nodes.
