I think you will need to post some sample code, and more details of your
setup to get any meaningful help. I can say, though, that we are doing
something similar to you - Server A is an ASP page under IIS, Server B is
perl CGI on Apache, and everything seems to be working well, and fast. I
did hear a rumour that serverXMLHTTP is very slow if the two "server"s are
in fact on the same server - i.e. if you have two ASP pages trying to talk
to each other on the same server - but I haven't done this myself so can't
comment.
Sorry I can't be of more help,
David.
