No, the base Horde app shouldn't be pinging anything under normal use  
(assuming no external APIs such as Weather or Twitter etc...) were  
configured for use in the Portal page . The only place I can think of  
that would do any kind of request is the configuration page, which  
might be polling pear.horde.org for updated packages if requested to  
do so.

Shot in the dark, as I haven't been reading this thread fully, but  
maybe it's related to compressing javascript and not being able to  
save the compressed file (so it must spend time compressing on each  
request)? Try temporarily turning off javascript and/or css caching  
maybe?

Another thought - have you tried just requesting a basic test script  
on the server to be sure it's not some issue/latency with PHP itself?
