Basic Pleskian
(a) This command took all sites down while it was running - not just mydomain.com/usr/local/psa/admin/bin/httpdmng --reconfigure-domain mydomain.com
(b) It took a few minutes - I seem to recall the old /usr/local/psa/admin/bin/websrvmng was a lot faster (but I had not used it for a few weeks before upgrading to Plesk 10).
The same thing happens when adding a customer through the Plesk panel.
Again I cannot recall this happening with Plesk 9.
Looking at the processes it is running things like:
/usr/bin/sw-engine -c /usr/local/psa/admin/conf/php.ini /usr/local/psa/admin/sbin/httpdmng --reconfigure-batch /usr/local/psa/tmp/httpdmng-batch-g1qYgq
