My node has been accepting around 59% of requests for the past 12 days. Just before that, it was accepting only a few percent. (I am still blacklisting nodes that do not backoff, by IP at the firewall, but I don't think that matters much now). I have 1.5gb RAM, 2GHz P4, DSL. Configuration parameters: threadFactory=Y storeSize=4096M outputBandwidthLimit=5400 maxNodeConnections=800 maximumThreads=500 defaultResetProbability=0.01 Every so often (maybe every 10 minutes) it drops to accepting only a few percent of requests, because of messageSendTimeRequest, but quickly recovers. Over the past 2 days, I averaged 9 nodes backed off (24 samples), max observed 28, out of 50 nodes in the RT. Recently I haven't seen any long backoff times. Since the inception of backoff, I averaged 17 nodes backed off (123 samples), max 34. Total pooled threads averaged 191 over past 2 days, and 128 since Sept. Largest number caught (which is probably not the maximum) was 370. Total data received is almost always more than data sent, but I note that those numbers are really data + overhead, not just trailers. outputBytes is often about 5 times outputBytesTrailingAttempted. Bytes waiting to be sent recent average is 100 MiB. That takes about 5 hours to send at 6k/sec. Recent probability of success of an incoming request Max (out of 16 bins) averaged 2.5%. Since Sept. it averaged 3%. Does this mean routing is not working? Maybe. Maybe it means 97% of requests are for nonexistent keys. Or maybe something in between. -- Ed Huff
