considering the fact that there are only 20 to 30 docs changed the
indexing is not the bottleneck. Bottleneck is probably the db and the
time taken for the query to run. Are there deltaQueries in the
sub-entities? if you can create a 'VIEW' in DB to identify the delta
it could be faster

Try using LuSql to create the index. It is 4-10 times faster on a
multicore machine, and can run in 1/20th the heap size Solr needs.
See slides 22-25 in this presentation comparing Solr DIH with LuSql:
