It seems to be some sort of DNS issue, but I don't know exactly what. An HTTP connection to www.anz.com.au takes about 45 seconds to establish, regardless of the browser. E.g. time telnet www.anz.com.au 80 Trying 202.2.59.40... Connected to www.anz.com. Escape character is '^]'. ^] telnet> quit Connection closed. real 0m44.633s A DNS query, however, responds almost immediately: time dig www.anz.com.au [...] ;; QUESTION SECTION: ;www.anz.com.au. IN A ;; ANSWER SECTION: www.anz.com.au. 9798 IN CNAME www.anz.com. www.anz.com. 1 IN A 202.2.59.40 www.anz.com. 1 IN A 202.2.56.40 [...] real 0m0.288s And an HTTP connection by IP number instead of by name responds almost immediately, also. I see no packets coming from them (e.g. IDENT queries) that would account for the delay. One of their IP numbers (202.2.56.40) has no PTR record, but I don't think that has anything to do with it. > > Another thread on this list "[kde-freebsd] Konqueror very slow displaying > some sites" puts it down to DNS.

I don't know if "dig" uses the native resolver or implements one of its own. I suspect the latter. - Bob
