Freenet 0.7.5 build 1437 is available, please let me know if you have any trouble updating. This build will be mandatory on the 28th of March.
The main change is an improvement to load management proposed years ago by Ian: Currently, when a node is overloaded, we send a "slow down" signal only when we reject requests, i.e. when the damage has already been done and requests have been routed to the wrong nodes because the right nodes are out of capacity. In 1437, we send the "slow down" signal (RejectedOverload with Local=false) when a peer is using 80% of our capacity for running requests, and I have increased the node's capacity accordingly. This should result in fewer rejections, and therefore more accurate routing, and hopefully better performance in general and in particular better data persistence. We have statistics to measure all of these things; the "fewer rejections" bit we can measure quickly, this is the main measurement of success for this change (operhiem1's graphs now show a graph of the proportion of nodes rejecting a given proportion of requests). Any change to general performance will take longer to show up. There may be a brief period of reduced performance while the network adapts to the new code; at worst, it should be back to normal shortly after the build is mandatory. There are also a few minor bug fixes. Thanks!
