Don't despair -- my result might be true only for low-latency grids! We already have lots of data showing that 1.8.0c3 is an improvement for large files on a real-world grid. I think it would be useful to try an experiment like mine on the pubgrid. But I'm nervous about the storage consumed there. We can't easily delete that storage, so I'd have to always use the same convergence file. But is there any behavioral impact when uploading a file that already exists on the grid? (It wouldn't be in the backupdb because I'd always use a fresh client, but the storage nodes would already have it.) Or, with a few volunteers not behind NAT, we could move my testing into a high-latency environment. (Alas I've noticed the way I stop nodes isn't totally reliable, so this might not be set-and-forget.) > I really hope that this was some sort of glitch in your test rig. > Could you please re-run this experiment a dozen times or so and post > the results? I'll run it continuously overnight and post the results. But I'll scale down from 40 storage nodes to 12; I think 10 nodes per machine was excessive. -- Kyle Markley _______________________________________________ tahoe-dev mailing list [email protected] http://tahoe-lafs.org/cgi-bin/mailman/listinfo/tahoe-dev
