Solr 4 near real time commit

[yu shen]

Hi All,

I tried using solr 4 nightly build: apache-solr-4.0-2011-12-06_08-52-46.
And try to enable autoSoftCommit like below in solrconfig.xml
<autoCommit>
    <maxTime>100000</maxTime>
</autoCommit>
<autoCommit>
    <maxTime>1000</maxTime>
</autoCommit>

I try to add a document to this solr instance using solrj client in the
nightly build. I do saw a commit time boost. Single document commit will
basically take around 10 - 15 seconds.

My question is, my configuration mean to do the commitment within 1 second,
why solr still takes 10 seconds.
