The http://myserver/describe/?url=resource service is very slow when
expecting a text/html answer. However the same request and expecting an
application/rdf+xml document is very fast.
For instance, the following request takes more than 1 minute
time curl -i -L -H "Accept: text/html"
while the next request takes only 5 seconds
time curl -i -L -H "Accept: application/rdf+xml"
This makes me think that the problem is in the configuration of the http
server or in the service transforming the rdf data into html. However I
have no clue about which parameters should be modified.
Does anyone know how I can solve this issue?
