as a shot in the dark, your servers might be making reverse lookups of IP to
DNS name for logging purposes (or if you call request.getRemoteHost()), and
if your DNS setup is performing slowly this might explain it. You don't
mention whether the HTML page itself is returned quickly or not. if it's
the reverse lookups that's the problem, I would expect it to be slow too.
>From the default 5.0.27 server.xml:
By default, DNS lookups are enabled when a web application calls
request.getRemoteHost(). This can have an adverse impact on
performance, so you can disable it by setting the
"enableLookups" attribute to "false". When DNS lookups are
disabled,
request.getRemoteHost() will return the String version of the
IP address of the remote client.
