Here's another data point (same ADSL connection) - The delicate point is: is plan9 at fault or it is the fact that it is advertised as Plan9 that is the source of this throttling down. Because I have tested retrieving a 10MB file from another server, under plan9 (http://mirrors.ctan.org/macros/latex/base.zip) and I have good results on par with what I have under NetBSD (same node; dualboot). So I think the ethernet layer (the rtl8169) is not at fault. Perhaps another IP layer is at fault (bad negociation under some circonstances leading to very small packets). Or the server is throttling down the connection, whether explicitely because it is Plan9/hget (used by some? as bittorrent utility, or the string used etc.) or simply because there is a rule that everything not recognized/authorized (ie, chrome, mozilla, wget, ftp, lftp) is considered a robot, and is throttled down... > > #l0: i82579: 1Gbps port 0xFE500000 irq 10: 386077f0e800 > 0.09u 0.08s 182.26r hget http://downloads.kergis.com/kertex/kertex_bundle.tar > > But on the same machine, using linux instead: > > $ time wget -o /dev/null http://downloads.kergis.com/kertex/kertex_bundle.tar > > real 0m9.134s > user 0m0.048s > sys 0m0.186s > -- Thierry Laronde http://www.kergis.com/ http://www.arts-po.fr/ Key fingerprint = 0FF7 E906 FBAF FE95 FD89 250D 52B1 AE95 6006 F40C
