long startup time

[Teruhiko Kurosaka]

I've been testing Solr 1.4.0 (RC).
After sometime, solr started to pause
for a long time (a minutes or two) after
printing:

        INFO:  jetty-6.1.3

Sometime it starts immediately, but more often
than not, it pasues.  Is there any known cause
of this kind of long pause?

How big is your index?  Can you share your solrconfig?  Have you  
looked at it in a profiler during this time?  What is it doing?

The index is almost empty; it only has index about the .xml files
in the exampledocs directory.  solrconf.xml has not been modified.
I have no idea what it is doing.  I guess I should use profiler to
find it out.

I'm not sure if anyone answered this.
The "2 minutes" makes me think it's a DNS lookup timeout.  Is something trying to look up some host name? (say from the top of some XML file)
