Trying to set up a server to host multiple Solr cores, we have run
into the issue of too many open files a few times. The 2nd ed "Lucene
in Action" book suggests using the compound file format to reduce the
required number of files when having multiple indexes, but mentions a
possible ~10% slow-down when indexing. Are there any other down-sides
to this? Seems to work by just changing this line in solrconfig.xml:
<mainIndex>
<!-- options specific to the main on-disk lucene index -->
<useCompoundFile>true</useCompoundFile>
