Okay how about this: There are reports of downloads taking a lot longer than people had hoped. Some have suggested this is "stalling". "Stalling" in the most literal sense, as I have previously debugged, would mean that particular requests are not getting selected AT ALL. The patch by oo's sole function is to increase the frequency of *trying to send requests*. It does not affect the client layer, where such stall supposedly would be. It does not affect the cooldown or RecentlyFailed logic. All it does is run the same code more frequently; this still has to get past e.g. local load limiting, and it still won't send requests for keys that are in cooldown. Yet this patch is universally praised as solving the problem. Conclusion? Requests are not stalling. Requests are being sent "too slowly" compared to some arbitrary expectation - maybe even compared to past performance. But they are still being sent. Having said that, there does seem to be an issue with bogus RecentlyFailed's, which needs looking into. >>> >>>> Perhaps there is a problem with the AIMD's.

I'm not the one that's calling for us to throw out load management principles based directly on TCP and replace them with ... what? The hope that it won't cause backoff everywhere? I don't see what your manifesto is. oo's patch, by effectively turning off sender-side load management, would increase load, and there is no reason to think this wouldn't be catastrophic. It's the equivalent of a tweaked TCP stack saying "damn congestion control, I'm just gonna send packets as fast as I can". There's a reason that real TCP stack don't do that. >>> >>> I don't think so as you fear to verify your assumptions like hell.

Months of coding? There really haven't been that many significant load-related changes over the last 18 months AFAIK. NLM was revoked. The period over which Freenet's performance is supposed to have collapsed coincides with a period in which my productivity has been substantially reduced (see below). So it's not due to my tinkering. Which means it either doesn't exist, or is due to something else. "There are too many unknown parameters": I sometimes use this phrase to explain why we can't get an accurate analysis of the impact of one build just by measuring insert/request performance: There is so much background noise that only a really big change will have a clear effect. That's not just my view, it's digger3's view too (and he maintains the stats). However, we can add specific stats to measure whether specific changes do what they are supposed to do. >>> >>> It is beyond my imagination that *you* are going to study mathematics, >>> that will be really interesting to follow.

There are no recent pictures of me anywhere on the internet AFAIK, including Freenet. And I'm not so proud as to think that I know everything, unlike certain people here. Nor am I so foolish to think that I'm incapable of learning anything new at the grand old age of 32. That's simply not true, for 3 reasons: 1. I have been successful so far in my recent education. 2. This week's New Scientist has a detailed article debunking the common fallacy that older people can't learn. 3. There are lots of mature students at Cambridge (and other prestigious universities too), and many of them do very well. Granted most "mature students" are early 20s, but many are much older, and still go on to get good degrees. They offered me a place, so I am confident that I can do well: I trust their judgement on that. > > I do not agree with your negative attitude. > > Stop stupid illogical personal attacks. > > We should be thankful for his dedication and work, even if it was not > always best.

I am hoping to make substantial progress after my exams are over, that is from June 22nd to the beginning of October.

And "where" its >> progressing to thats still not clear. I have documented most of my medium term goals for Freenet in some detail in various forums - bug trackers, IRC logs, mailing lists. There is a reasonably clear vision. Granted, none of these things is really an acceptable form of documentation. However the near term priorities should be IMHO: - Client layer: Get rid of db4o, and replace it with something more robust and faster. - Darknet: Make it easy, fast, and secure. - Tunneling: Darknet-based tunnels could provide us with some fairly impressive security for inserts. - Load management. We've discussed this. The current TCP-based model is wrong, but removing one section of it without looking at the rest doesn't work. Changing the other areas as well, so that "too many requests" doesn't result in "backed off hell", may work well. > > That is correct. > > So we are here to help develop Freenet and give more freedom to people. > > Instead just bitching you could give us your time, or money, or something. > > I would guess that you or your friends are at creating some patches, this > is very good and I'm sure we will get around to use them.

Yes, the main reason Freenet doesn't make rapid progress is because we have limited person-power. We simply need more developers. Money is one way to do that, but the best way is to get more volunteers.
