Another data point: this helped us greatly.  I added the following to the
FastCGIFAQ page, and changed the examples below to match -- can someone
fact-check me please?

    Q: Why is RT under FastCGI so sloooooooow? When using a progressive-rending
    browser like Firefox I see the entries appear slowly, one at a time, but
    the server doesn't appear to be overloaded and the database is not large.

    A: You might only have spawned one mason_handler.fcgi, which would cause
    all the httpd processes to block, waiting for it to service them. Make sure
    you use an appropriate "-processes X" option in your FastCgiServer
    directive, as shown below. You should have as many mason_handler.fcgi
    processes as the nominal number of httpds that are usually running
    (StartServers <= "-processes" <= MaxSpareServers)
