Every time a commit is done a new searcher is opened. In the solr config file
caches are defined with a parameter called autowarm. Autowarm basically tries
to copy the cache values from previous searcher into the current one. If you
are doing a bulk update and do not care for searching till your indexing is
over then you can specify openSearcher=false while doing a commit. That should
speed up your indexing a lot.
