Thanks. No, I can't say for certain when this started. In fact, reverting to a kernel from June 27 still shows the same problem. However, I have done the following exercise, with three machines, two of which sit on our internal LAN together, on the same hub, with the third sitting on our public network (in our hosting room). Configs being: hangdog: - 5.0-CURRENT, 128M RAM, PII-266 (internal LAN) deadpoint: - 4.3-STABLE, 128M RAM, PI-166 (internal LAN) illuminati: - 4.2-RELEASE, 128M RAM, PII-333 (public network) hangdog and deadpoint sit on the same hub at my desk. There are 3 router hops from my hub to the hosting network - one of those hops being a firewall. All three machines are running IPFW. I did a test of downloading a 240M odd file from one machine to the other as a test. Everything looked fine, until I used hangdog (my -CURRENT box) as the server. I aborted that download, as it was too painfully slow. The transfer rates were as follows: Server Client ------ ------ illuminati -> deadpoint (4.2 -> 4.3) 852kBps illuminati -> hangdog (4.2 -> 5.0) 788kBps hangdog -> deadpoint (5.0 -> 4.3) 83kBps Thus, it appears that -CURRENT is still doing OK as a client, but is struggling badly as a server. At this point, this seems, from the empirical evidence, to have nothing to do with ACPI.
