Unless you leave yourself enough outbound bandwidth for snappy delivery of requests and acks for inbound sessions, performance suffers tragically. Bandwidth limiting apache to maybe 400kbit/s should leave you plenty of headroom (unless you're uploading torrents too :) > I do not wish to take my website down and so I was hoping somebody would > be able to tell me if it is possible to throttle apache's upload speed. > It seems that this would provide a good solution - people will need to > wait a little longer to see my page, but a change of waiting 3 seconds > to waiting 6 seconds isn't terrible. > > My router does not appear to have the option to throttle individual > hosts/ports. Any advice on the matter would be appreciated. The apache module should do that job. For a more generic solution (and perhaps anyway, given some crazed robots will suck down your whole site xty times a day, if allowed) a firewall with pipe/queue management, like Jeff's pf+altq, or ipfw+dummynet, can provide more fine-grained control. cheers, Ian
