I use solr in my application, there is just hundreds of documents. the memory usage is about 80M, how to reduce it?
回答1:
80M is not much, in fact it's pretty much the mininum, you won't go much lower than that.
Some factors that affect memory usage:
- Input document size
- Multi-threaded document updates
- Cache size
- Facet queries
- Sorting
