Also, can you do your deletes via IndexWriter (delete by Term) instead
of opening IndexReader to do the deletes?

Did you get anywhere with this? 3 secs for one delete is excessive. A
job of mine ran earlier today and did 2000+ deletes by term on unique
id in less than 9 seconds. The index is smaller, at around 5Gb, but I
don't believe that would explain the difference. All the deletes were
done in one batch using lucene 2.3.2.
Is there a lot of other concurrent activity on the index? On the
server? Is it CPU or IO bound?

Dear List,
I have a rather big index around 20gb. My documents have a unique id
that I store in in an untokenized field.
Using an IndexReader I delete documents by term using the id. The
applications tries to batch as many delete operations as possible for
this.
The applications runs on a 8Core Machine with 1GB heapsize for the
JVM. Each delete takes about 3sec to complete. I have a lot of
Updates
during a day so this takes a lot of time and in effect this is too
slow.
Is there anything I can do to speed things up a little?
Best,
Michael
