Subject Slow deleteById request
Date Tue, 01 Jul 2008 12:54:21 GMT
Hi,

We experience very slow delete, taking more than 10 seconds. A delete is 
executed using deleteById (from Solrj or from curl), at the same time 
documents are being added.
By looking at the log (below), it seems that a delete by ID request is 
only executed during the next commit (done automatically every 1000 
added documents), and that the process (Solrj or curl) executing the 
deleteById request is blocked until the commit is performed.

Is it a normal behavior or a misconfiguration of our Solr server ?

Thanks in advance for insights.
