[TYPO3-performance] Deleting pages in Backend extremely slow

I had such a issue just a few days ago. The Solr Extension sends direct
commands to the Server on different occasions such as delete a page or
hide/unhide elements. As this particular Solr Core has a quite big
amount of data in it those queries took about 10 seconds which leds to
the described behaviour.

I have not looked that far into it, but maybe the Solr Extension should
write those commands into the indexing queue as well.
